British Airways Check-In: Online Check-In, Times and Common Problems

British Airways online and app check-in normally opens 24 hours before departure. Start with the official checking-in page or Manage My Booking, then follow any direction to the operating airline or airport desk.

A booking is not fully ready for travel merely because it appears as confirmed. Before leaving for the airport, verify that a valid e-ticket has been issued, identify the airline operating the first flight, complete passport or travel-document requirements, and obtain a valid boarding pass for every available flight segment. Check-in is not complete until the boarding pass contains a scannable barcode or the airline specifically instructs the passenger to collect it at the airport.

This independent guide is not the airline's check-in portal. For broader fare, seating and connection planning, see the British Airways flights guide.

• Confirm the correct airline booking reference rather than assuming an agency reference is interchangeable.
• Check that every passenger has a valid e-ticket attached to the intended segments.
• Identify the airline operating the first flight and the check-in channel it provides.
• Have the passenger surname, passport and required entry information ready.
• Review the exact website or app error and whether document verification is required.

The British Airways Manage Booking guide explains how to find a reservation, distinguish references and confirm ticket issuance before check-in.

1. 1

   Open the official channel

   Use the airline's official website, app or the operating-airline link supplied for the itinerary.

2. 2

   Retrieve the booking

   Enter the correct six-character airline reference and passenger surname, or use the authenticated app where appropriate.

3. 3

   Confirm passengers and flights

   Select only the passengers and segments intended for check-in.

4. 4

   Complete required information

   Enter or verify passport, Advance Passenger Information and declarations directly with the airline.

5. 5

   Review seats and documents

   Confirm any available seat choice and read airport or document-check instructions.

6. 6

   Save every available pass

   Download or print each boarding pass and confirm that it contains a scannable code.

The British Airways app can store boarding passes for eligible return and connecting flights departing within 24 hours. Availability still depends on the itinerary and airport.

Airline-documented limitations

• Check-in has not yet opened, or online check-in is unavailable from the departure airport.
• Passport, visa, entry-permission or Advance Passenger Information requires verification.
• The booking is a charter or another restricted booking type.
• Young people aged 14 or 15 travelling alone cannot check in online. At some airports, British Airways also directs groups of more than nine passengers and families with a child on a separate booking to a kiosk or check-in desk, so passengers should follow the instructions for their departure airport.
• A connecting boarding pass cannot be issued online or the airline directs the passenger to an airport desk.

Our practical troubleshooting checks

• The wrong agency, British Airways or partner-airline reference is being used.
• The surname format does not match the reservation.
• The ticket was not issued, or a changed ticket was not successfully reissued.
• The first flight is partner-operated and uses another check-in path.
• Recorded assistance or medical arrangements require airport discussion.
• The itinerary has changed or been disrupted, or the website or app has a temporary problem.

If British Airways check in online is not working, do not repeatedly alter the booking. Confirm ticket status and the operating carrier, try a fresh official session, and follow any instruction to collect the boarding pass at the airport.

A British Airways booking reference is six characters made from letters and numbers; the airline states that its references do not contain 0 or 1. An agency or partner may supply a different record locator.

The ticket number is separate. A visible reservation does not itself prove ticketing, so confirm a valid e-ticket from the receipt or airline or agency record. The ticket number is not required to appear on a boarding pass and should not be confused with the scannable boarding-pass code.

British Airways check in without a booking reference may be possible at some airport kiosks using a passport, but online access normally requires the relevant airline reference. Ask the issuing provider for the correct locator rather than guessing.

Read the 'Operated by' line for every segment. Some American Airlines and Iberia-operated flights with a British Airways flight number support check-in through ba.com; other British Airways partner airline check-in journeys may redirect to the operating airline.

The passenger may need both British Airways and operating-airline confirmation numbers. Check each segment rather than assuming one boarding pass covers the whole journey.

Illustrative scenario

Consider a BA-marketed itinerary beginning with an American Airlines-operated flight. If British Airways does not issue the boarding pass, the passenger confirms ticketing, checks the operating carrier, locates the American Airlines confirmation number and follows that airline's check-in path. They verify boarding passes for every available connection and, if still unsuccessful, arrive early for airport assistance. This is an illustrative scenario, not an actual agency case.

Airport check-in may be required when online check-in is unavailable, documents must be inspected, a boarding pass cannot be issued, special arrangements need discussion or the operating airline directs the passenger to a desk.

Bring the correct passport, booking details and travel documents. Airport staff may issue the pass only after confirming that the passenger meets the applicable requirements. A direction to collect a pass at the airport is not, by itself, proof that the ticket is invalid.

• A scannable barcode or mobile boarding-pass code
• Passenger name, flight number and departure date
• Origin, destination and terminal
• Gate when available, seat when assigned and boarding group where displayed
• Boarding and gate-closing information
• A pass for every passenger and every available flight segment
• The TSA PreCheck indicator where applicable

Gate information may be blank when the pass is issued, and gates or seats can change. Recheck airport screens and the airline app. A booking reference may appear on the pass, but it does not prove that an e-ticket was issued; verify ticketing from the receipt or booking record.

British Airways participates in TSA PreCheck for eligible passengers departing from participating US airports. A Known Traveller Number may be added through Manage My Booking during online check-in, at an airport desk or through the airline's contact channel.

Adding a KTN does not guarantee TSA PreCheck or expedited screening. Verify that the TSA PreCheck indicator appears on the boarding pass. Treat the KTN as confidential and do not place it in messages or article content unnecessarily.

Check-in and bag-drop closing times vary by airport and route. British Airways directs passengers to Manage My Booking for the exact deadline; missing it can prevent travel even when online check-in opened 24 hours earlier.

As practical agency guidance, we generally recommend arriving around three hours before an international departure. This is not a universal British Airways deadline. London City advises passengers not to arrive earlier than two hours before departure, and other airports operate differently.

Allow additional practical time when checking baggage, travelling with children, requiring mobility assistance or travelling during disruption. Review baggage limits and bag-drop preparation in the British Airways baggage allowance guide.

Whether seat selection is free depends on the fare, cabin, status and operating carrier. Many eligible passengers can choose an available standard seat when check-in opens. Economy Basic passengers are normally assigned seats and do not receive the same free-selection entitlement.

Families seeking particular seats together may choose them earlier where offered, although fees can apply. Availability at check-in is not guaranteed, and partner-operated flights follow the operating carrier's seating rules.

British Airways says it aims to seat families together and that each child under 12 will be seated next to an adult from the same booking. A family may still be split across rows or an aisle. Travellers over 12 are treated as adults by the seating system, and separate booking references may prevent the system from recognising one family group.

Free seat selection is not automatic whenever wheelchair assistance is requested. It can apply when a passenger has a specific disability-related seating requirement after the assistance need is recorded. British Airways recommends requesting assistance at least 48 hours before departure; some seating requests require direct airline contact, and safety or exit-row restrictions still apply.

Partner-operated flights use the operating carrier's assistance and seating policies. Verify the request and seat with each relevant airline rather than assuming that one record update has propagated.

In our agency workflow, we first inspect the fare rules and identify who issued and controls the ticket. A preliminary alternative-flight search may be possible without modifying the reservation, but a checked-in passenger normally must be removed from check-in before the ticket can be formally repriced, changed or reissued.

Cancelling check-in does not cancel the ticket. The old boarding pass becomes invalid after check-in cancellation or a flight change, and the passenger must check in again after reissue. Obtain authorization before cancelling check-in or modifying the booking.

We explain fare differences, airline penalties and any applicable agency service fee separately. If baggage has been dropped, departure is close or a partner operates the flight, airport or operating-airline staff may need to take control. This is our operational process, not a universal self-service method published by the airline.

The British Airways flight changes and cancellations guide explains fare-rule, issuer and no-show considerations in more detail. The agency refund policy applies to agency handling and is not the airline's refund policy.

Passengers can normally complete online check-in themselves through the British Airways website, BA app or the operating airline's official channel without paying an agency. If a passenger requests agent-assisted check-in support, an agency service fee may apply. We explain the exact fee and obtain authorization before beginning; it is our agency fee, not a British Airways charge, and is separate from airline baggage, seating or airport fees.

Payment does not guarantee a boarding pass or permission to travel. The Fare Disclosure explains price presentation, and the Post-Ticketing Service Fees page explains agency fees that may apply after ticketing.

• Obtain clear, time-specific authorization for the named passengers and segments.
• Treat permission to view as separate from permission to check in, cancel check-in or pay for a service.
• Collect only information reasonably necessary and use an authorized agency or airline channel.
• Never request or store a British Airways Club password or log in with customer credentials.
• Obtain the passenger's direct confirmation for travel-document and dangerous-goods declarations.
• Do not retain passport copies when entering required details is sufficient.
• Restrict access to passport numbers, KTN and government identifiers, then delete or de-identify information when no longer needed, subject to lawful retention requirements.
• Obtain appropriate consent for other adults; a parent or guardian may authorize assistance for a minor.
• Send the boarding pass securely and record the authorization and work completed.
