Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Baggage check in was very slow. No sign that the check in was TAP until the station opened. Understaffed and overworked team.
