I needed assistance from plane and it was excellent service.

New modern plane, but seats very tight. Little room, especially uncomfortable on long flight. Also seemed quite warm in the cabin.

Much better than my last experience on Aer Lingus through Expedia. January I had a horrendous trip.

Food very good. Not sure if we were on BA or AA. Nice plane. Seats could have more room. Very nice flight
