Great staff.

Dec 15, 2019

I had the most unexpected smooth experience at the airport, from no line at TSA pre-check, to getting assigned a seat at the last min next to this guy that was cool and friendly to talk to, to cozily watching two movies (Toy Story 4 and Booksmart), to the flight attendants coming by frequently with drinks and snacks and having a cup of red wine on the plane. This is completely unlike the United Airlines of that terrible viral video kicking the man off with security guards and my parents describing their trip to China with disgust at the staff. This also changes my opinion of United. . .wow!

I didn’t get dragged off the plane. That’s a plus.

Food was not worth the time serving it.

Oct 22, 2019

The no luggage on the flight for basic is just plain bad, and unrealistic for international flights. I probably didn't save money since I had to check one piece.

Great flying A to B at reasonable price. Food was the worst. Please, stop with the pretentious cuisine. It's awful! Keep it simple: ham sandwich, KFC, whatever. Something edible please!

Overall very happy, but the wifi on the flight was underwhelming. Couldn't do much more than send emails
