The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Crew Very nice people, The food was mediocre. Entertainment outdated. The English of the announcements were very hard to understand. Luckily there was nothing serious.

The flight crew was top notch. Total professionals, they worked to help everyone fit their luggage on board and get comfortable. Like many European airlines, dinner service included wine with no extra charge. Always a nice touch. On our layover, everyone needed to clear passport control, which looks like a horrible time sink when you have a connection. My compliments to the ground crew who tried to move people with tight connects to the front of the line. I don't know whether they were Air Portugal employees or not, but they were some people's heroes. I'm not a fan of airline pricing that doesn't give you a reasonably realistic idea of your total cost. Checked baggage on Air Portugal is very expensive and negates any other price advantage. Seat selection is also quite costly. My biggest complaint about this airline is their boarding process. There is no info available to passengers on the screens in the boarding lounges. Just long lines that stretch into other gate areas and too few people offering any clarifying info at all. Those who try to direct often ended up yelling into the crowd. On my last leg, they called for boarding groups over the PA system, but when I presented myself, I was sent back to the end of the single line even though others in later groups were ahead of me. It was a confusing mashup of two systems that left everyone disgruntled and took over an hour. I don't think I can recommend this airline if you have any other options.

Tap air portugal first has you pay for the flight. Then you realize that seats are extra. Had i known that i would have booked emirates instead for a few dollars more

Dreadful - queued to get onto a bus, stood for 10 minutes on the bus, drove to the plane, stood for another 25 minutes on the bus outside the plane. When allowed on we could only board from the front & were seated in the furthest row back. The second bus was allowed to board from the back so chaos ensued!. The flight was an hour late - nobody said why, nobody apologised. On arrival at Heathrow we stood for nearly 30 minutes before being allowed off - again with no explanation,

Efficiency was great - on-time takeoff and landing. Baggage arrived at destination (there's always slow baggage handling in Boston.) TAP food is spartan - bring your own. But the efficiency of the airline more than makes up for the mediocre cuisine.

On-time flight. Nothing out of the ordinary. The food offering upfront could be better.

Delayed takeoff was inconvenient. We should have boardrd later. Coffee/ beverage service on a 7:30 flight would have been good.

Flight from Lisbon to Barcelona was ok. Business flight Boston to Lisbon was awful. Attendants should pay more attention to Business Passengers and not be so stingy with water. Worse Business Flight I have ever taken. Food was awful. Cramped for space.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

Good, everything went straight forward and on time, I am satisfied

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.

Everything went according to plan. Check in, boarding etc all were very efficient.

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

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

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 🤷‍♀️

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

On time, no announcement all along the flight, you can rest.
