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

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

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

Easy process and good flight experience The food good be better

I didn't like. The seats and the floor were very dirty and it is not the first time

Unfortunately didn't realise how far away Frankfurt Hahn airport is from Frankfurt the city. Outbound flight was delayed by 2.5 hours and no communication at airport, just a whisper emknating through the packed crowd ready to board at the gate as someone read out an email they had received. All rather poor and pathetic

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

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

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

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

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

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.

Very Stress free Lounges were superb. Crews were caring. I loved it.
