The crew was excellent. The food was not good. I have taken many international flights and the meal was not good by comparison.

The crew was excellent. The food was not good. I have taken many international flights and the meal was not good by comparison.

On both flights, TAP Air Portugal messed up the seating choices that I paid for. They acknowledged that I had purchased seating, that they were errant in ensuring my choices, but told me nothing could be done about it. When I asked to be refunded, I was directed to "talk to someone from Air Portugal" Mon-Friday, and then I was dismissed. No help, no phone number provided to me. I was very annoyed both times and feel cheated.

The worst thing was baggage claim. In my return flight I was waiting 90 minutes for my baggage. and when I asked the airport they said it’s the airline. So frustrating after an 8-hour flight.

Business class seats aren't comfortable. Food was not good.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

Chaotic boarding with no announcements. Carry on luggage needs to be checked. Bare minimum zero frill flights. Not a whole lot of anything positive to be said .

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Delayed at the beginning and the end and almost missed our connection

Menzies group staff not very sympathetic good at breaking up families during the boarding process

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.
