Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

I was told to be there to check in three hours before my flight and the counter only opened up two hours before. Apparently that is standard. So that was an hour I could have spent walking around Larnaca that was wasted. But besides that it was great

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

I enjoyed the comfort of Premium Economy. The Purser on London-Nairobi was a little testy, snappish in his tone. I understand stressed, tired, etc but his tone in addressing passengers I found wanting.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

British Airways Flight 525 from Florence to London on July 29th 2025 was the worse flight I have ever been on. The flight was excessively delayed with poor communication from airline as to the reason for delay. We were notified of need for an unscheduled stop in Pisa after boarding due to weather which was limiting ability to fuel up to the capacity needed for the flight to London. Though we understand and appreciate the safety concern, on quick web search we later learned this was a recurrent problem. We were subsequently kicked off our connecting flight out of London to Port land, Oregon (also on British Airways) though that flight was also delayed (we were told we would not be able to make it in time, but ironically the amount of time it took for them to rebook us would have been more than sufficient to make the connection). We then had to stay overnight in London at a very mediocre hotel, had to take a flight out on a different carrier which involved a stop at LAX (not a direct flight to our home city which we had paid extra for the convenience). Half of our bags did not arrive in LA and we had to transfer the bags ourselves from the international terminal to terminal 6, only to have most of this luggage that made it from London to LAX not arrive in Portland. They bags were eventually found but took over 60 hours for delivery. The entire trip home which was suppose to be 13 hours took over 40.
