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.

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

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Boarding time was a bit slow causing the flight to not leave right at 5 pm,but other than that it was fine.

Web site needs improvement Plane was clean and modern Lay Flat beds were hard and not to comfortable (business class )

Overall, everything was fine—the service, the food, and the entertainment—but the boarding process in Lisbon was a total mess. I’m not sure I’d fly with TAP again. It’s absurd to have to pay for good seats at the front of the plane only to board last; the overhead bins above your seat are likely already full thanks to passengers who boarded earlier—even though they might be seated at the back of the plane. I will think very carefully before flying with TAP Portugal again; it seems to me that they need to review their boarding process. I understand the logic of filling the plane from back to front, but the seats at the front are more expensive. Horacio Rodriguez

Boarding was delayed by one hour because cleaning and catering crews did not board the plane in time. Take off was delayed for another 40 minutes because of "rush hour scheduling". Vague descriptiion. My in-flight entertainment system was stuck initializing. The flight attendant indicated that they could not reset it without resetting everyone's system. Overall, a miserable experience.

The cabin crew was very courteous, professional, and courteous. Great service!

Better leg room than expected in economy. Nice crew. Adequate bathrooms. Seat cushions a little thin, but recline well and have adjustable headrests. Best value. Liked having nonstop from ORD to Lisbon.

Excellent! Flight left a bit late but overall a pleasant experience.

Let’s be honest. You know you are boarding a flight where the seats don’t recline and you need to pay double the price for bread, gin and water. But beware, they test your tolerance to torture pre boarding. They call all British passport holders. Then tag cabin luggage to be checked. And the ground staff pretend not to know what is happening and just says - please ask the other staff.

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.

Didn't get to go because connection flight was cancelled

The airline gets you from one place to another in a reasonable time. Not much more you can expect.

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

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

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

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.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.
