Airline reviews

First they postponed the departure from 20.20 to 02.05 - almost 6 hours. Then all communication stopped. At app. 23.30 all info boards confirmed that the plane was finally cancelled. And after a sleepless night I realised that two contradicting messages had been received: At 01.59 passengers were directed to board - at the opposite end of CPH Airport - as the plane would take-off at 02.05 and at 02.42 CPH Airport Authority (official traffic information) confirmed that plane was again-again cancelled. Irreparable image!

It's fine if you don't want to give free water or anything, but don't try to sell the food in first class like there is a chef that actively made the food from the finest local ingredients. Its still plane food and the chef hasn't been near that food for quite some time

I was very disappointed because a special assistance wasn’t given to me and water was given to me in 50 min after I asked about it.Poor service,

Smooth flight. Surprisingly good and inexpensive food choices. Clean cabin. The plane is not equipped with the entertainment system.

Failure of APU meant massive delays at start of journey , baking in an unventilated plane Not good

Delay ca 5 hours on the first flight and 2 hours on the next one

The airline ran late and I almost missed this connecting flight to LGW. The airline didn't act very sympathetic to my situation. I wished that didn't happen as my experience I'm sure would've been much different.

One flight has delayed, but connecting flight ( the same company) has another plan for us. And left TO TLL. Instead Finnair.Who waiting pax from BRUSSELS. GREAT EXAMPLE OF COOPERATION. 👍

Great leg room and very clean plane nothing could be better 😁

We flew TAP last October from Newark to Lisbon. The meal was bad. This flight had good food. Also, this flight was delayed. There were TAP employees waiting at Lisbon to make sure we made our connecting flight. I find the TAP website and app frustrating, but the service once we reached the airport was very good

The airport temperature at the airport and on the flight was too warm

Boarding too way too long. Biggest peeve: zero in-seat power in economy! No plug sockets, no USB ports. Plane was an A330, so not old.

boarding is so disorganized, i was literally appalled at the boarding experience

Comfortable but not Polaris or Delta comfort Business Class. Overall 7 out of 10

Tap air Portugal was the best I will traveling again with u guys. Thank u.

The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying

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.

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

I’ve never had worse food in business class ever!

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.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

Delayed and changed Multiple times after booking necessitating many. Travel changes ; a bit of an issue

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

They lost a bag and now our vacation is ruined

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

The crew was caring and attentive in making my flight comfortable as I was travelling with an injury.

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

It was great. The airline staff was very friendly. The FRA security was a bit harsh doing their job but friendly overall.

Everything went really well. Snacks could be better and there was no tea/coffee service after dinner. Crew was helpful and friendly.

Lufthansa charged me $280 to take skiiis when in the US the boot bag and skiis are one check-in bag. This was not advertised and a real shock at the airport. They only took the boot bag as a check-in item. The seats have been squeezed together like any economy airline and legroom is not as good as it used to be. Otherwise, the flight was fine and staff was helpful for making my connection.

I have ordered Hindu or Indian vegetarian food, to my surprise they did not find any such request. All I ate during the flight was 2 pieces of bread. The airline hostess was completely rude and racist. She promised one apple and I asked he four hours of promise and she denied saying am not nice to her. Europeans seems to be having racism issues with Indians. I will officially launch complaint with Indian and USA governments They made to starve, I recently got open heart surgery and I am diabetic patient

The plane was late and had not been cleaned prior to our flight from Frankfurt to LA, so we had to use bathrooms that were completely filthy and stank like hell. One of them eventually was even closed early on during the flight. It was a horrific experience.

Delayed flight with no explanations; no jetway boarding so we had to stand on the tarmac in the cold rain. Baggage was lost.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!
