Verified travelerFlew with British AirwaysPRG-LHRJul 2025
British Airways does not allow for check-in through app or website. There is a message that passports need to be scanned, but no way to do it. Check-in was unavailable at airport kiosks, so we had to do it in person at the desk. Not a huge deal, but allow plenty of time! Also a bit stressful if you want to choose/change/buy a seat as it is very last minute.
AnnaFlew with British AirwaysPRG-LHROct 2024
Dont get to Prague airport too early if you are checking a bag because they dont even tell you where you can go to check you bag until just a little before the flight. We sat and waited for no reason
Verified travelerFlew with British AirwaysPRG-LHRJul 2024
The signs on posts in the Prague airport aren't tall enough, so if there are people in queue who happen to be in front of the signs, they're easy to miss. These signs are important to know which line one must use for ticketing: ticketing, bag drop, or level of passenger.

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

Very bad.i will never book British flights for future

Moved me away from my family and refused to fix it.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Must have had an elderly tour on the trip. Plane boarded via tarmac and had both front and tail stairway access. We waited about ten minutes at the rear entrance while elderly folks entered the forward access and walked all the way back to last rows of the aircraft! We could not access the row until every one of them finally reached the final rows. There should have been an agent directing folks Forward and Aft based on seat row. It was comical.

The airport experience at check-in, just to drop a bag, was horrible. The were two agents working, two watching. We stood in line for just short of one hour. I asked the agent if this were normal and he said, "Well, yes. Just two computer terminals." No apologies. BA needs to fix this ASAP. Meanwhile, I've moved BA to the very bottom of my booking list.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?

Tickets get checked 4 separate times by different staff, would save time if only the person at the entrance and the person who scans the tickets checks them!

I have always been pleased with their service. Would not change a thing
