Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

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

They left our luggage uncovered on tarmac in pouring rain during an hour delay of departure! At our final destination, we found ALL OF OUR CLOTHES/SHOES soaked all the way through!! Our 1st connection plane was a great business class accommodation but only 50 minutes long. Our 2nd connection from Lisbon (another delay with luggage uncovered on tarmac) had only the extra legroom and mediocre food in business class - no entertainment and no extra comfort seating. Will not use TAP Air Portugal again!

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Shady baggage policy that forces you to pay more money at the gate, even after you checked your bag dimensions during the bag drop. Will never fly again with this airline.

Guide passenger if fhey board from front or back door cause it was a total mess

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.
