The check in process at the front desk felt slow and it was frustrating that we could not check in online. Everything about the actual flight was great, including very kind flight attendants and a nice larger bathroom. Only thing is that it was very cold in the plane!

I flew economy class. Seats were very good and the crew was excellent

I had a great experience. I would definitely use them again

The pre-check (passport control) for all US flights from Dublin airport is brilliant, meaning these flights come into the domestic airport in the US - it was so quick and easy getting to my hotel once we landed. The plane itself was great, staff were lovely and food was fine.

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

One of the best flight experience I have had in along time. Would fly with them again.

Like getting a bus. No great luxury but will get you there

Got us to destination alive, albeit a bit late. Luggage was left behind. No live tracking app available (available on some other airlines). Supposedly going to be delivered in next couple of days.

The trip was mostly nice, till the last moment when they had some issue with opening the flight door. The flight arrived late by 10 minutes, which was ok-ish, but then we got stuck on the plane for 35 minutes at the bridge and that costed our connection flight to LAX which left with 12+ passengers still on our flight. It added 2 days to our trip home, and we had to make lots of rearrangements to deal with the ripple effects. Don't book a 1+ stop trip with a layover time less than 2 hours.
