KAYAK customer support can help with KAYAK account access, Trips, Price Alerts, search results, website errors, inaccurate prices, feedback and suspected scams. KAYAK does not currently publish a general consumer customer-service phone number or email address. Its official support routes are the KAYAK Help Center, feedback form and online chat.

For a flight, hotel, rental car or vacation package reservation, the company that issued the booking and charged the payment normally handles confirmation emails, changes, cancellations, refunds and invoices. KAYAK is primarily a travel search engine rather than the airline, hotel, rental company or online travel agency providing the reservation.

What Is KAYAK?

KAYAK is a travel search and comparison service. It searches offers from airlines, hotels, rental-car companies and online travel agencies and displays available options in one place.

KAYAK can be used to compare:

Flights
Hotels and other accommodations
Rental cars
Vacation packages
Cruises where available
Travel dates and destinations
Prices from multiple booking providers

KAYAK also provides tools such as Trips, Price Alerts, flight tracking, Explore, travel guides and AI-assisted trip planning.

Is KAYAK a Travel Agency?

KAYAK describes itself as a travel search engine, not the provider of the flight, hotel, rental car or package displayed in its results.

In most cases:

KAYAK displays and compares the offer.
The traveler selects a provider.
The airline, hotel, rental company or online travel agency issues the booking.
The selected provider charges the payment.
The provider sends the confirmation.
The provider controls changes, cancellations and refunds.

Some reservations can be completed while the traveler remains on the KAYAK website. These bookings are still fulfilled by a third-party provider, and that provider normally handles post-purchase support.

Contact KAYAK About:

Search-result errors
An inaccurate displayed price

Rental-car changes
Refund eligibility

KAYAK generally cannot modify or refund a reservation merely because the travel option was found through KAYAK.

How to Find Out Who You Booked With

Travelers sometimes remember using KAYAK but not which airline, hotel website or online travel agency completed the reservation.

Search the email inbox for the destination, hotel, airline and travel dates.
Check spam, junk, promotions and deleted-email folders.
Review the credit-card or bank statement.
Identify the merchant name attached to the charge.
Check the browser history from the booking date.
Open KAYAK’s Booking Receipts page if the booking was completed while signed in.

Contact the hotel directly and ask which provider supplied the reservation.
Rerun the original KAYAK search to help identify providers that were displayed.

The company shown as the merchant on the payment statement is usually the best starting point for locating the reservation and resolving a charge.

How to Find a KAYAK Booking Receipt

Bookings completed while signed in and remaining on KAYAK with a participating provider may appear on the Booking Receipts page.

Sign in to the KAYAK account used during checkout.
Open the Booking Receipts page.
Locate the trip or transaction.
Review the confirmation and provider information.
Use the listed provider support route for changes, cancellations or refunds.

Only eligible bookings completed while signed in may appear. A reservation completed after KAYAK redirected the traveler to another website may not be stored in KAYAK’s booking history.

KAYAK Booking Confirmation Never Arrived

Check spam and junk folders.
Search for the airline, hotel, rental company and destination.
Check whether the payment is pending or completed.
Review KAYAK Booking Receipts when applicable.
Identify the merchant on the payment statement.
Check browser history to find the booking website.
Contact that provider and request that the confirmation be resent.

Do not immediately repeat the booking solely because the email is missing. The first reservation may have been completed even though the message was delayed or filtered.

My Card Was Charged but I Have No Confirmation

Determine whether the transaction is a temporary authorization or a completed charge.

Then:

Identify the company shown beside the charge.
Search email for that company’s name.
Check KAYAK Booking Receipts when applicable.
Contact the merchant that processed the payment.
Provide the amount, transaction date, traveler name and email used.
Ask whether a reservation was created.
Request written confirmation or reversal of an unsuccessful charge.
Contact the bank when the transaction remains unknown or unauthorized.

KAYAK normally cannot locate an off-site reservation using only a KAYAK search because the provider controls the booking record.

How to Change or Cancel a Flight Found on KAYAK

Identify the airline or travel agency that issued the ticket.
Locate the confirmation and ticket number.
Review the fare rules.
Check whether the booking includes separate one-way tickets.
Contact the issuing provider.
Ask about change fees, fare differences, credits and refund eligibility.
Confirm changes in writing.
Verify every segment of the updated itinerary.

KAYAK does not set airline change or cancellation fees and generally cannot alter a ticket issued by another company.

How to Cancel a Hotel Found Through KAYAK

Identify whether the hotel or an online travel agency processed the booking.
Read the cancellation terms in the confirmation.
Check the hotel’s local cancellation deadline.
Contact the booking provider.
Request a cancellation number.
Save the cancellation email.
Monitor any deposit or prepaid refund.

Calling the hotel can help identify the booking provider, but the hotel may be unable to refund a payment collected by a separate online travel agency.

How to Change or Cancel a Rental Car Found on KAYAK

Contact the rental company or booking website that issued the reservation.

Before changing or canceling, review:

Prepaid or pay-at-counter status
Cancellation deadline
No-show rules
Pickup time
Driver age requirements
Deposit terms
Required identification
Credit-card requirements
Location-specific fees

KAYAK cannot normally modify a rental reservation controlled by another company.

How to Request a Refund for Travel Found on KAYAK

The company that issued and charged for the booking controls the refund.

Identify the booking provider.
Review the cancellation and refund rules.
Cancel through the provider when required.
Ask whether the refund is cash, card credit or travel credit.

Request the refund amount and processing date in writing.
Save all cancellation and refund confirmations.
Monitor the original payment method.
Contact the provider if the promised refund is delayed.
Contact the card issuer before its dispute deadline when appropriate.

Submitting feedback to KAYAK does not replace a refund request made to the airline, hotel, rental company or online travel agency.

KAYAK Price Changed During Checkout

Travel prices and availability can change between a KAYAK search and the provider’s checkout page.

Possible reasons include:

Another traveler purchased the remaining inventory.
The provider updated its fare or room rate.
Taxes or mandatory fees were added at checkout.
The search displayed an older cached price.
The selected baggage or fare option changed.
The displayed currency differed from the final payment currency.
The provider’s availability data was incorrect.
The offer applied only to a limited number of travelers or rooms.

Do not complete the purchase until reviewing the final provider name, itinerary, cancellation terms, fees, currency and total.

How to Report an Incorrect KAYAK Price

Use KAYAK’s inaccurate-price form and include:

Screenshot of the KAYAK result
Screenshot of the provider’s checkout page
Visible website addresses
Search dates and destination
Number of travelers or rooms
Travel class or room type
Provider name
Displayed KAYAK price
Provider’s final price
Currency
Date and approximate time of the search

Reporting an inaccurate price allows KAYAK to investigate its search results but does not guarantee that the provider will honor the earlier displayed amount.

KAYAK Price Alert Problems

Price Alerts notify users about changes in tracked travel searches but do not reserve or guarantee a price.

When alerts are missing:

Sign in to the correct KAYAK account.
Review notification preferences.
Check spam and promotions folders.
Confirm that the Price Alert remains active.
Verify the destination and travel dates.
Check mobile push-notification permissions.
Contact KAYAK through the feedback form if alerts still fail.

A lower-price alert does not mean the fare will remain available until the traveler completes the purchase.

Price Dropped After I Booked

KAYAK does not normally issue a refund when a provider’s price drops after purchase.

Contact the booking provider and ask whether its terms include:

A price guarantee
A free cancellation period
A fare-difference credit
A rebooking option
A hotel price-match policy
A rental-car cancellation and rebooking option

Consider cancellation fees, lost benefits and the risk that the lower offer may disappear before canceling an existing reservation.

KAYAK Hacker Fare Changes and Cancellations

A KAYAK Hacker Fare can combine two separate one-way tickets to create a round trip. The tickets may be issued by different airlines or under separate reservations.

Important risks include:

Each ticket has separate change and cancellation rules.
Canceling one ticket does not automatically cancel the other.
One airline may not protect the other ticket after a disruption.
Baggage may need to be collected and rechecked.
A missed outbound flight may not cancel the separate return ticket.

Schedule changes may need to be handled with multiple providers.

Contact every airline or issuing agency involved before changing a Hacker Fare itinerary.

KAYAK Overcharge or Duplicate Charge

First determine whether the transactions are pending authorizations or completed charges.

Compare transaction dates and amounts.
Check for multiple bookings.
Review every confirmation email.
Identify the merchant shown on each charge.
Contact that merchant directly.
Ask whether one transaction is a temporary authorization.
Request correction of any completed duplicate.
Contact the card issuer if the merchant does not resolve it.

Only the company that processed the payment can normally issue the refund or transaction correction.

How to Get a Travel Invoice

KAYAK generally cannot issue an airline, hotel or rental-car invoice because it did not process the payment.

Request the invoice from:

The airline shown on the ticket or statement
The hotel when it collected the payment directly
The online travel agency that charged the card
The rental-car company or prepaid booking provider
The package seller

Provide the reservation number, traveler name, transaction date and billing details requested through the provider’s secure channel.

KAYAK Account Login and Verification Codes

KAYAK currently uses emailed verification codes instead of traditional account passwords.

Open the official KAYAK sign-in page.
Enter the account email address.
Request a verification code.
Check the inbox and spam folder.
Use the newest code received.
Confirm that the code was requested from the official KAYAK domain.

Add an optional passkey from the Account page after signing in.

Never give a verification code to an unexpected caller or message sender. A code can provide access to saved Trips and account information.

Why Did KAYAK Create an Account for Me?

Forwarding a travel confirmation to trips@kayak.com can automatically create a KAYAK account for the sending email address.

KAYAK sends a verification message so the user can confirm and access the account. This may explain why someone receives account or Trips emails even though they do not remember manually registering.

How to Delete a KAYAK Account

Sign in to the KAYAK account.
Open the Account page.
Scroll to the bottom.
Select Delete Account.
Review what account information and Trips may be removed.
Confirm the deletion.

Deleting a KAYAK account does not cancel a flight, hotel or rental-car booking. Contact each travel provider separately about active reservations.

When the goal is only to stop promotional email, change the notification settings instead of deleting the entire account.

How to Stop KAYAK Emails and Price Alerts

Use the unsubscribe link in a KAYAK marketing email.
Sign in and open the Notifications page.
Turn off selected newsletters or Price Alerts.
Disable KAYAK push notifications through the device settings.
Reply STOP to an eligible KAYAK text message.

Service messages connected with Trips, account security or active travel may continue even after marketing emails are disabled.

KAYAK Trip Is Missing

KAYAK Trips can organize confirmations from airlines, hotels, rental companies and other travel websites.

If a forwarded receipt is missing:

Sign out and sign back in.
Confirm which email address was used to forward the receipt.

Make sure it matches the KAYAK account email.
Forward the confirmation yourself rather than having the provider send it directly.
Add and verify an additional sending email in Trips Settings when needed.
Check that the message is a booking confirmation or receipt.

Forward it again to trips@kayak.com.
Contact KAYAK through the Help Center if it remains missing.

Adding a reservation to Trips organizes the itinerary but does not transfer control of the booking from the original provider to KAYAK.

KAYAK Trips Privacy and Sharing

Trips may contain flight numbers, hotel details, confirmation information and traveler schedules.

Share a Trip only with people who need access.
Review whether a recipient receives viewing or editing permission.
Do not post a public screenshot containing confirmation details.
Remove access when collaboration is no longer needed.
Protect the connected email account.
Secure any calendar feed used to sync Trips.

A calendar subscription link or shared itinerary may expose travel dates if it is forwarded to an unintended person.

KAYAK App Is Not Working

Confirm that the device has internet access.
Close and reopen the app.
Install the latest KAYAK app update.
Restart the device.
Sign out and request a new verification code.
Check location, notification and cellular-data permissions.
Try the KAYAK website in a current browser.
Record the error and app version.
Use the feedback form when the problem continues.

Do not delete saved emails or provider confirmations merely because they also appear in the KAYAK app. Keep an independent copy of important travel records.

KAYAK for Business Support

KAYAK for Business is separate from ordinary consumer travel search. The appropriate support route may depend on the employer’s travel program and provider configuration.

Business travelers should:

Open the trip in KAYAK for Business.
Look for a Manage Booking option.
Review the company travel policy.
Contact the listed travel provider or agent.
Contact the employer’s travel administrator.
Use any dedicated company support channel shown in the account.

A general KAYAK feedback request may not replace the employer’s contracted travel-support service.

KAYAK Booking and Job Scams

KAYAK warns about scammers impersonating the company through calls, email, WhatsApp, Instagram, LinkedIn and lookalike websites.

KAYAK states that it will not:

Contact a traveler by WhatsApp to complete a booking.
Request direct payment to KAYAK for a flight or hotel.
Ask a job applicant to pay an application or training fee.
Require payment to activate a job.
Request card information through an unsolicited recruitment message.
Recruit from a free Gmail or Yahoo email address.

Official KAYAK recruitment email should use an address ending in @kayak.com. Lookalike names such as “kayakworking,” “kayakonline” or “kayakagent” should be treated cautiously.

What to Do About a Fake KAYAK Message

Stop communicating with the sender.
Do not send money or identification.
Do not install remote-access software.
Save the message, sender address and website.
Change passwords if credentials were entered.
Secure the connected email account.
Contact the bank immediately if money was sent.
Report the message through KAYAK’s feedback form.
Report fraud to the appropriate government or law-enforcement agency.

A company asking for payment is not made legitimate merely because it displays the KAYAK logo or names a real KAYAK executive.

How to Escalate a KAYAK Complaint

Determine whether the complaint concerns KAYAK or a travel provider.
Use KAYAK’s feedback form for a search, account, Trips, pricing or website issue.

Use chat when available.
Contact the booking provider for reservation changes, refunds or invoices.
Provide screenshots and the exact search or booking details.
Ask the provider for a case number.
Save all confirmations and responses.
Request review by a supervisor when the responsible provider does not address the documented issue.
Contact the payment issuer before its dispute deadline when a charge remains unauthorized or a promised refund is not issued.

Use KAYAK’s current Stamford address only for final written correspondence concerning KAYAK itself.

A review submitted to CustomerServiceNumbers.com does not contact KAYAK, identify a provider, cancel a reservation, issue a refund or open a support case.

KAYAK Customer Service Reviews and Complaints

CustomerServiceNumbers.com currently shows one KAYAK review with an overall rating of 3.0 out of 5. The review was submitted in May 2018.

The reviewer said a telephone representative would assist only with existing reservations and questioned why KAYAK did not provide telephone help with making a new booking.

This is an older individual experience. KAYAK’s current official help information says the company does not publish a general consumer customer-service phone number and directs users to its feedback form and chat. KAYAK also describes itself as a travel search engine rather than the travel agency issuing most reservations.

One 2018 review is not enough to establish a current KAYAK customer-service trend. New reviews can help readers understand current experiences involving the feedback form, chat, Booking Receipts, Trips, Price Alerts, provider identification and scam reporting.

KAYAK Privacy and Scam Warnings

Use an official KAYAK domain before entering account information.
Do not trust an unofficial telephone number merely because it appears in a search result.
Do not post a booking confirmation, ticket number or payment statement publicly.
Do not share an account verification code.
Do not provide a passport, driver’s license or tax document to an unsolicited recruiter.

Do not pay KAYAK directly for an ordinary flight, hotel or rental-car booking.
Do not send money for a KAYAK job, equipment package or training fee.
Do not allow an unknown representative to control a device remotely.

Verify the actual airline, hotel, rental company or travel agency before paying.
Review the final provider, itinerary, currency, fees and cancellation policy at checkout.
A public review does not reach KAYAK or the booking provider.

Kayak Booking Help Unavailable by Phone – Reservation‑Only Service

May 4, 2018

I called Kayak’s customer service, and they only help with existing reservations. Since Kayak is a booking agency, why can’t they assist with new bookings over the phone? What are customers supposed to do if they don’t have a computer? Are they just out of luck?
