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.

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.

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.

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

Take off was great but landing is always with a bump.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

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

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Worst experience ever. First time and last time with Ryanair. I'm not a cow.

Everything was OK but I got the feeling that the aisle seat in row 3 is smaller than the other 2 seats

Good flight. Take off a little late but make up the time

O voo atrasou um bom bocado A tripulação não era comunicativa,não fez vendas... Não abordava os passageiros... A 1°vez que me acontece tal coisa 🤷‍♀️

Bag check in was terrible. Arrived 2 hours and 10 minutes ahead of required time and then waited 50 minutes in line to check ONE bag. There were 4 employees standing around as only two were checking bags and there were 6 gates available to check bags. Process is terrible. Lack of customer concern and service.
