Checking in at Heathrow Terminal 5 (which is almost exclusively used by British Airways) is a highly automated experience in 2026. Upon entering the massive "Check-in" hall on the top floor, you will find hundreds of self-service kiosks. You scan your passport, print your boarding pass (if you don't have a mobile one), and, most importantly, print your own bag tags. After tagging your luggage, you proceed to the "Auto Bag Drop" zones, where you place your bag on the belt and scan your boarding pass to send it to the aircraft. For "Club World" or "First" passengers, there are dedicated staffed counters and a "First Wing" that provides a private security channel. If you are flying economy, the "human interaction" is kept to a minimum unless you have a document issue. It is highly recommended to check in via the British Airways app 24 hours in advance to secure your seat and then simply use the kiosks for bag tags to save time in what is one of Europe's busiest terminals.
Excellent question! Checking in at Heathrow Terminal 5 is straightforward, but the process varies depending on your airline and whether you have hold luggage. Here’s a step-by-step guide.
Terminal 5 is the home of British Airways and Iberia. A few other partner airlines also use it, but the vast majority of flights are BA. The process is largely the same for all airlines there.
The terminal is split into two main buildings: Terminal 5A: The main building for check-in and most flights. Terminal 5B & 5C: Satellite buildings for some departing flights. You reach these via an underground transit train after security.
Your first stop is always Terminal 5A.
