Airline reviews

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

I thought Miami's airport was very disorganized during the Boarding.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

People seated in exit rows should have designated overhead space

I have been flying internationally for most of like. My first trip with TAP- wonderful! I look forward to flying with them more frequently in the future!

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

Flight was 2+ hrs late boarding. Delay updates were nonexistent. Boarding Gate change was by word of mouth.

The plane was modern and clean. TAP staff at the airport as well as the flight crew were professional, friendly, and helpful. Overall, a great experience.

The airline made last minute changes to our business class seats splitting our family of 4 with young children who had pre-booked a row of 4 seats. The seat was also dirty and sticky. Our pre-ordered child meals were also not available. :(

Awful experience all around, misleading booking led to disgraceful baggage charge at gate. Tiny uncomfortable seats with little drinks served in small paper cups filled halfway. Difficult to use bathrooms the whole flight and now on the way back we’re stuck in Lisbon a day later because of a diversion on our connecting flight, I will never fly this airline again.

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

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

Ryanair is the worst airline in Europe and easily one of the worst in the planet

Em relação a Ryanair, ter de ir ao check-in só para carimbar o cartão de embarque não foi muito fácil, são muito demorados, e atrasam a passagem do controlo de passaporte... E cheguei com 2 horas de antecedência

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

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.
