Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Coming from the EU to the USA, Aer Lingus is a very good choice. You clear U.S. border control while still at the departure airport, so when you land in the States, you don’t need to go through the entry process again — very efficient and fast. In terms of comfort, Aer Lingus is better than the usual EU carriers like KLM, Lufthansa, or Air France, and also better than United. There’s more legroom, and the crew is helpful and kind. The food is average but slightly better than most airlines. Overall, the crew is definitely better than on American Airlines, though not quite at the level of Virgin.

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.

We had a long delay leaving IOM. No food or drunk service as it is a short flight. Shuttled by bus from terminal to plane with packed in conditions on bus.

The space between seats was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.
