Book direct unless the third-party offer earns the extra layer

Search first, then make a separate transaction decision. Google Flights, Skyscanner and KAYAK can show several sellers for the same itinerary. The lowest headline is not automatically the lowest complete trip, and the most familiar search interface is not necessarily the company that will charge you or answer a change request.

Our best flight search sites comparison helps find and compare the itinerary. This guide begins at the next step: choosing whether the airline or a third party should take payment and service the booking. For a deeper look at U.S. merchant-of-record servicing, credits and data handling, see who serves your ticket when you book direct or through an agency.

Airline direct vs third party at a glance

The search site is not always the seller

Google Travel Help says selecting an offer usually takes the traveller to an airline or online travel agency to complete the transaction. It tells customers to contact that airline or travel agent to confirm, change or cancel the booking. Google also warns that fees can vary by the booking option selected.

Skyscanner likewise says it is a search engine and does not process the booking. Its help page tells travellers to identify the company in the confirmation email or card statement and use that provider as the first point of contact. KAYAK says payment and booking happen on the partner's site after its comparison handoff.

Changes and cancellations expose the difference

A voluntary change is governed first by the fare you bought, then by the service route attached to the booking. A non-refundable or restrictive ticket does not become flexible when bought direct. An OTA cannot waive an airline's fare rule merely because it sold the ticket.

The extra layer can still matter. British Airways tells customers who booked through a travel agent or travel website to contact that seller, and its name-change answer says BA cannot change tickets they issued. Booking.com's terms say most flights on its platform use a third-party aggregator and that help with a change or cancellation depends on the contract of carriage.

If flexibility matters, compare the actual fare in our refundable vs non-refundable flights guide before comparing sellers. Seller simplicity cannot repair a fare that never allowed the change you want.

Refund rights and refund paths are separate

Entitlement and process are separate. A law or fare rule may establish that money is owed, while the merchant of record determines who returns it in practice. Keep the confirmation, e-ticket, fare rules, receipt and card statement so you can identify both the operating airline and the business that took payment.

Do not assume every refund passes from airline to agency to traveller. The U.S. Department of Transportation defines the merchant of record as the entity shown on the payment statement and says that merchant is responsible for owed airfare refunds on covered cancellations or significant changes. The merchant can be the airline or ticket agent. Optional service and bag fees are different: DOT says those refunds must be requested from the airline even after an agency sale.

UK261 and ATOL protect different risks

The UK Civil Aviation Authority defines UK passenger-rights coverage by route and airline: flights departing the UK on any airline, arriving in the UK on a UK or EU airline, or arriving in the EU on a UK airline. For a covered cancellation, the airline must offer care and a choice of refund or an alternative flight. Those flight-disruption rights should not be confused with ATOL, which protects against the failure of an ATOL holder for qualifying bookings.

ATOL is not automatic because a website is a travel agency. ATOL's official guidance says a normal airline ticket issued as a valid e-ticket in exchange for payment is not covered by the scheme. A protected booking should produce an ATOL Certificate naming the holder. Check the certificate, not an OTA logo or a general protection claim.

U.S. refund rules depend on the merchant of record

DOT says a consumer is entitled to a refund when an airline cancels or significantly changes a flight and the consumer declines the changed flight, rebooking, credit or other compensation. For a ticket-agent sale, the airfare refund duty falls on the airline or agent that is the merchant of record for a flight to, from or within the United States.

The familiar 24-hour rule needs special care. For tickets bought at least seven days before departure, an airline must offer either a 24-hour hold or penalty-free cancellation. DOT says that requirement does not apply to tickets booked through an online travel agency or other agent, although an agent can voluntarily offer a similar policy. See the full 24-hour cancellation guide for the scope and exceptions.

Who should book direct or use a third party

• Book direct when totals are close, plans may change, the itinerary is complex or you value one obvious support route.
• Consider a third party when the identical all-in itinerary is materially better or a qualifying package adds protection you understand.
• Avoid the cheapest unknown seller when its legal name, contact route, ticketing role or refund terms are unclear.
• Use extra caution with separate tickets because a seller's support cannot create missed-connection protection that the itinerary lacks.

Limits and exceptions to the default

• Direct is not always simpler. Codeshares, partner flights and airline holidays can still involve several businesses.
• Third parties are not one category. Agency, reseller, aggregator and package-organiser relationships differ.
• Consumer law depends on scope. Route, operating carrier, seller, country and product structure can change the remedy.
• Terms change. The checkout, confirmation and current policy pages control the exact booking, not a generic comparison.

How we checked this comparison

We reviewed official Google Travel Help, Skyscanner Help and KAYAK Help pages for booking handoffs; British Airways and Booking.com pages for representative airline and OTA service terms; and current CAA, ATOL and U.S. DOT guidance for consumer protection. Every page was checked on 19 October 2026.

We did not run a fare benchmark, rank customer service or claim that one channel is always cheaper. Expedia's official terms page returned a bot challenge during checking, so no Expedia-specific policy appears here. The recommendation is based on fewer servicing layers, not an invented price or support score.

A checkout checklist before you pay

1. Match the itinerary. Use the same flight numbers, airports, dates, cabin, fare family and passengers.
2. Build the full total. Add bags, seats, payment charges, currency costs and any agency service fee.
3. Name every party. Record the operating carrier, ticketing carrier, seller, intermediary and merchant of record.
4. Read the change path. Check who handles voluntary changes, airline disruption and an owed refund.
5. Save the evidence. Keep the checkout terms, confirmation, e-ticket and protection certificate before closing the page.

If you are not ready to transact, keep searching or save the exact trip as a Watch. A Watch can flag a matching fare, but you still choose the airline or booking provider and verify the current terms before paying.
