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.

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.

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

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

The first leg of my 2 flights were delayed, causing me to miss my second flight and have to stay the whole night in Dublin. Super upset with this experience, and I still need to figure out how to get compensated for this.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

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.

It was raining and we got all soaked because the staircases didn’t had a roof

Would be better if there is phone charging ports available

Would have been a very good flight, but busses did not meet the plane at the destination airport (NAP/Naples) for nearly one-half hour after landing. Clearly the airport concessionaire’s fault, not RyanAir’s.

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.

Delayed flight. Received notice from ryanair by email and via app but no such timely information available at airport from monitors or staff

We arrived at the airport by taxi so as to be there two hours ahead of take-off. On arrival I received a message stating that the flight would be 85 minutes later than planned. An hour later another message stated that it would be a further 20 minutes late. There was no mention of the almost 2 hour delay once we boarded. Needless to say, they didn’t trumpet their “arrive-on-time” signal. At least we got there eventually.

I haven't had a ok flight with Ryanair in so long!

Full flight but no issues. Had priority boarding and everything was fine

Flight was delayed which happens but walking 15 mins to one gate to be then told it’s now changed to one 15 mins back then other way was frustrating

This was yet another excellent experience thanks to Ryanair, it's ground crew, cabin crew and air crew. Although our flight was delayed by about 15 minutes due to the late arrival of the inbound flight, the crew did their best to successfully minimise the delay with courtesy and efficiency. I also commend Ryanair for its choice of destination airport in this instance: Seve Ballesteros Airport in Santander is a modern, compact, well-kep and well-organised airport, where passing through security and passport control was a doodle thanks to its friendly and efficient staff. So take a bow, Ryanair - and keep it up!

Food and entertainment non existent as we were only in the air 25 mins so totally understandable

Flight delay of 4 1/2 hours with no reason for over 3 hours. Missed our connection in Rome & had to pay for an additional flight.

The lack of organization at the boarding gate was shocking. It was impossible to determine where the line was and it was hard to understand the announcements. It was so confusing that my wife wanted to get on the wrong flight. I am also annoyed that BA is adopting the sleazy policies that the budget airlines invented of charging extra for even the first checked bag or choosing your seat.

I never was able to take this cancelled flight…all flights from Zagreb were cancelled at 3:30 AM of departure day 9/8!

Experience was probably the best I’ve had on BA for a long time. Only thing is A380 is old now and it needs upgrading. The en re attainment screens are very small and the touchscreen barely works.

Aircraft delayed for two hours due to a technical issue with the rear emergency exit door slide not working.

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.

A late notice on the departure board of a last minute gate change from A gates to C gates was particularly challenging for us. We are senior citizens who ambulate just fine, at our pace. This late notice caused all of us to run, or in our case, walk as quickly as we could from Gates A to the transit train then down an another long concourse. Anyone with mobility issues or needing a cane to walk would not have made it on their own and they wouldn’t have had enough time to coordinate wheelchairs. At first I thought this was just “how it goes” at airports, until I noticed a text I received on my trip-it app that notified me of this gate change- WELL ahead of the departure boards in the airport. Had I be paying attention to my app instead of the AIRPORT’S information system we would have been able to move on with ease and composed instead of ‘trotting quickly’ and agitated at the new gate.. I see this as a flaw in either the airport’s arrival/departure board system or in BA’s communication to the airport. Either way, there is a LOT of room for improvement.

Pilots seemed fine but one stewardess seemed crabby, but it was tolerable just didn't seem to be projecting a service attitude. I understand we all have those days. Return flight on 8/8/24 noticeable better / normal.
