Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

Boarding took less than 20 minutes total. They offered free snacks and drinks soon after cruising. They offered more refreshments an hour before landing. This was a 3 hour flight. I haven’t seen this post-COVID. I will be flying KLM more often. The cabin was clean and flight attendants were very nice.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Good experience, just i couldn’t connect me to the wifi

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

Seats actually fit a human! Snack options were a bit lame but that’s ok

They blocked me from checking in online and they charged me lots of money

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

Check in was excellent thanks to the team at the check in counter. I was disappointed to see that one has to pay for coffee on the flight. This is the first time I have seen that after 60 years of flying.

Our steward Margarida who served us from Lisbon to Boston was absolutely fantastic! She deserves a raise. Conscientious and thorough as well as showing appropriate attention for every need.

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

Our flight from NY was on time. The leg room was torture.. for a long flight.. It was extremely uncomfortable.

Plane was late and they forced us to take the stairs (no elevator available) to catch the bus to the plane. My wife was carrying a baby and fell. Terrible experience and terrible air line. Constantly late and conditions seem to be getting worse every time I have to use them.

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!

This flight was delayed by more than an hour. The seats are uncomfortable ans do not recline properly. I prepurchased a wifi pass, but wifi was not working on this flight at all. The food was bland.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

All flights with Air Europa you arrive late to the connections of other flights, I missed my train, I had to pay for my train again, the crew are antisocial, you are paying for a service, it is not free, thanks to the travelers they are there, it is the last time I fly with them,

Very small dinner, NO breakfast. You have to buy an earphone.

The flight, the staff and the airplane were all fantastic. I highly recommend.

Service on plane was appalling. Cabin crew did not want to help with anything. Window darkening screen did not work so we had to sit in the sun for a few hours until it went down. TV screen did not work and cabin crew just shrugged their shoulders and did not care. We waited for over 2 hours for headphones so we could try watch one screen between 2 people. We had to go to back of plane to request basic water as crew never responded to call request. Will be letting many others know to warn them off ever using Air Europa. Total disaster of their own making

Impossible to check in via the App. Kept on getting emails offering upgrade. When followed through not available. Wasn't any food anyway.

Great experience, I just wish airline seats were more comfortable in general.

Onboarding process and crew was excellent and efficient, Information display was great. Keep on the good work and same standard. Nothing to change.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

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.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Well... Our flight departed with more than 3 hours delay from Beauvais.

I haven't had a ok flight with Ryanair in so long!

50 minute of delay on a flight scheduled after 22pm is really annoying. This was even the only flight departing from Frankfurt Hahn on that evening so the delay was inexcusable

Unfortunately didn't realise how far away Frankfurt Hahn airport is from Frankfurt the city. Outbound flight was delayed by 2.5 hours and no communication at airport, just a whisper emknating through the packed crowd ready to board at the gate as someone read out an email they had received. All rather poor and pathetic

There was no entertainment or food service (short flight). The flight was delayed more than an hour.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

Lufthansa has a bag policy unique to Lufthansa. We all had a small carry on and a backpack (personal item) that we carried with us through multiple other connecting flights, no problem. With Lufthansa we were charged 80 euros each for the carry on at the gate, for this one flight. When asked they said they made an announcement… problem being that we had just arrived to the gate from a connecting flight and didn’t hear an announcement. While we were standing at the counter paying the ridiculous fee several other people were stopped, while countless others boarded with the same type of luggage and were not stopped. Crazy. Good news though, when we got on the plane half of the overhead bins were empty! After an already horrible experience the lady at the counter was also terrible, so that helped round things out.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

Boarding arrangement at Frankfurt was terribly managed with no proper guidance and the flight was parked far away from the gate. In flight entertainment device (touch screen) was not working at all throughout the flight. And on top of all this two of the checked in bags were found to be missing when we landed at Chennai. All this mismanagement at a very high fare of about $2300 per ticket is unacceptable.

Water in bottle and a piece of chocolate were given. We did have movies to watch.

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

I was served cheese that had mold on it. I brought this to the flight attendants attention and she informed her supervisor. They were apologetic and offered me a replacement, but I think that is extremely insufficient compensation given I ate bad cheese causing food poisoning for my birthday vacation. Both me and the flight attendants photographed the cheese, and I was told they’ll “put in a ticket” to ensure it doesn’t happen to someone else…….
