The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.
