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.

Changed flight terminals/gates twice. The staff and hospitality was good.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

Used to be my "go to" airline but would be my last choice these days. I think some of the cabin crew believe it would be a great job if it wasn't for the customers.

I love travelling with British airways because everything is supper goog

Not that great. There were no entertainment screens, internet, or any way to track the flight path. The seats were fixed in order not to recline at all. The crew and the staff at the check-in counters were the only nice thing.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

my flight was canceled and rescheduled for two days later

They oversold and down graded me from Premium economy to coach. 75-pound compensation is insufficient if you chose a particular class. I get dehydrated and severe Charley Horse cramps. I requested a bottle of water, even half even less… but no- “We are only allowed to give water by the glass. Nonsense. Lastly, their planes now have a fixed barrier between seats. So even if your entire row is empty, you are confined to just your space. Lastly, London now requires a transit visa for $30 for US citizens. Never travel through London again

I love British Airlines but I think it’s time for a change.My seat was occupied by very large passengers sitting next to me,I felt very uncomfortable and very bad.I’m sorry but I have to say it.

We had to pay extra for seats and bags (even for an international flight). I paid for extra comfort seats, but it was under an overhead bin that the crew used for supplies. I paid extra hoping to get sleep. We were constantly woken up by the crew opening and closing the bins. Our seat shouldn't be considered extra comfort. We paid significantly more than the rest of the cabin for these seats
