Usually fly UAL in first but had to fly Delta today from Sea to SFO. Was on the new A220 in first and have to admit, it is an excellent product. The seat is very comfortable with leg room. While I did not eat - I usually pass - my seatmate did, and it looked very good. What impressed me was the seat. I like the Embraer seats in first but this was better. Flew up on the UAL Airbus yesterday, and I do not like that seat in first.
