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

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.

I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.

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.

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets
