The flight was excellent and we appreciate that they ran the flight even though only 9 of us were on board!

The flight was excellent and we appreciate that they ran the flight even though only 9 of us were on board!

Excellent round trip from London Gatwick to Newquay Cornwall! Personable staff and crew, bags made it, flights on time. For me it was 5 stars.

For a small aircraft the choice of food and drinks was excellent compared to other ATR 72 operators. Checked in baggage as standard means easy boarding and disembarking for all.

I shall never book a budget airline flight ever again. Saturday morning flight to Belfast cancelled, rescheduled for following day, arriving 25 minutes before scheduled departure flight. I made the mistake of buying a non-flexible, non-refundable ticket options were so much more expensive. Alternative options offered by KAYAK did not come close in any way to my original booking; My first and last attempt to book a flight through Kayak.

Every flight on this airline is delayed, generally upto 2 hours for an internal flight. Very poor and absolute logistical disaster.

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.

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.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

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.

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

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Well Is extra charge for everything and other companies include that and the price.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

You booked my 7 year old son to sit on his own without his mum and dad in s separate row between two unfriendly adult strangers. The plane was disgusting and dirty, aisles and everywhere sticky. The lounge waiting area was filthy carpet and had insufficient seats so we had to sit on it to wait for 35 minutes and my 7 year old sone played on this filthy lounge carpet. The outside of the plane appeared clean. The pilot was helpful with the route and what to expect weather etc.

Comfort isn’t a word one uses on economy airlines! Boarding was okay, delayed but okay, the flight was good, quick and time was made up.

The seat leg room seemed much tighter on the way home My cheese toasty wasn’t that hot - didn’t realise till half eaten

With stairs on a rainy tarmac, EasyJet flights are ok for younger travelers with backpack only. Seniors with mobility issues find it challenging 😰. However, the crew and disability assistance folks at both ends eased that discomfort as much as possible for their various roles. Kudos to airport and EasyJet employees for their kind service.

The flight boarded a little late but made up the time in flight - much appreciated. The staff were efficient and fairly friendly One of the toilets wasn’t working - having only one functioning toilet for a flight of hundreds isn’t really acceptable. I still find it amazing that the budget airlines can’t even offer free tap water to passengers.

Plane out was great, one back was cramped. Awful. Thankfully great crew!

Nothing flight was on time, and we boarded and disembarked easily

Pros: "Quick boarding and landed earlier than scheduled."
Cons: "The air-con was too cold. The seats don't allow you to sleep as there's no where to rest your head against."

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

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.

The seats were uncomfortable. It was an old plane. The crew could have been more hospitable.

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.

I declined a wheelchair in Vienna as I was told it was a short walk. However, though I "boarded" the bus first, I was at the back when we got to the plane. There were steps up to the plane and no-one helped except the stewardess as I was near the top of the stairs. She found a better seat for me also.

Horrible connection in Heathrow on flight to destination. Flight missed due to delay on incoming flight. They did rebook us, and then that flight was delayed 2 hours. They don’t post gate info until 45 minutes to departure time which can cut it close if you have to take a tram to your terminal gate area. Then our return flight was completely cancelled. They notified us at 4:30AM. They rebooked us on a different airline and a different fare class. We were completely screwed. Travel day ended up being 30 hours. I will never fly them again.

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!

There's no inflight entertainment, plane was old, power USB didn't work
