Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug in was broken, especially we are with 5 years old who like to watch a movie

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

App totally screwed me up trying to check in. Would not let me select a reasonable seat and therefore I was stuck in a totally uncomfortable seat for 7 hours. Will not take the chance again and use other airlines in future where no issue choosing seats

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

Not being stuck in the middle seat between strangers but that’s not the airlines fault

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

I was at the airport 10 hour early. I would have loved to drop luggage in advance but this was possible only 3h before the scheduled time, however BA was so kind to move me to the earlier flight as it had space available at no extra cost. Thank you!

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.
