British Airways offers a variety of convenient check-in options to suit every traveler. Passengers can check in online or through the mobile app starting 24 hours before their flight. Online check-in allows travelers to choose seats, add baggage, and receive boarding passes digitally, which can be saved on a phone or printed. Those traveling with only carry-on luggage and who have checked in online can go straight to security without visiting the check-in desk. For passengers who prefer to check in at the airport, self-service kiosks and staffed counters are available. Airport check-in counters typically open three hours before international flights and two hours before domestic flights. It is important to arrive early, as counters usually close 60 minutes before long-haul departures and 45 minutes before short-haul flights. British Airways also provides an overnight bag drop service at select airports, letting travelers drop off checked baggage the evening before their flight to save time on departure day. Additionally, the AirPortr service allows passengers in some cities to have their luggage picked up from home or hotel and delivered directly to the airport. Passengers should ensure they have all required travel documents such as passports and visas ready before arriving at the airport. Boarding gates close about 20 to 30 minutes before the flight departs, so it is recommended to be at the gate well in advance. For help or questions regarding check-in, customers can contact British Airways at +1-866-551-1186. By following these procedures, travelers can enjoy a smooth and efficient check-in experience with British Airways.
