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.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

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.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Very good need to offer better choice of food for business

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.
