Boarding experience was awful. TAP claims I did not have check in luggage with tickets. I went 3-4 check in agents until I finally found a helpful kind agent who checked in my luggage with no fees. On top of that our flight was over 2 hours delayed with barely an apology or explanation.

Boarding experience was awful. TAP claims I did not have check in luggage with tickets. I went 3-4 check in agents until I finally found a helpful kind agent who checked in my luggage with no fees. On top of that our flight was over 2 hours delayed with barely an apology or explanation.

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

Flight being delayed for 35 minutes had me lose the connection to my transport

Was the best airplane ✈️ ever that I never see I will traveling again again with u guys.

Flight from FNC to OBO was cancelled. We were rebooked to Lisbon later in the day. It was inconvenient but it worked out ok in the end.

Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.

Very pleasant flight, crew was very nice. The flight was really smooth, big plane. The seats are kind of close together, so comfort was just OK. The boarding process on the way back to New York was a little chaotic. It took a long time.There were no announcements, no loudspeaker just one staff yelling out of instructions and a lot of people crowding in before their term to board. So that could really be improved a lot.

The crew was very nice. The food was good. The entertainment on the way back to Miami wasn’t as good as the flight over. I wanted to watch Wicked but on the way over from Miami to Lisbon but the screen didn’t work. On the way from Lisbon to Miami Wicked wasn’t an option. Liked the option to check out overhead carry on with our checked luggage Overall the flights were very good. I would fly TaP again

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

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.

After passing through boarding gates we had to wait for 45 minutes in a small space with no place to sit.

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Crazy long boarding times, messy, inexperienced, overworked, and visibly tired crew, very uncomfortable seats and no compensation for delays.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Our luggage arrived 2 days late when we reached Santorini. We were without cloths and toiletries for two days and didn't had time or means to go and shop everything at reasonable cost. Even though, we filed the report immediately at the airport, there was very less communication to us about when we would expected our luggage and even when it arrived there, they didn't had staff to deliver luggage to our hotel, so we had to go to airport to pick it up, which is very difficult and annoying to do in foreign country where you don't have you own vehicle and you don't have time because your tour is packed with activities. They could have tried to expedite the process and kept us informed and deliver the luggage at our hotel. Also, should have given us compensation for it.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Very old aircraft. Seat 15 A & B personal light not working, foot rest broken in 15 A , reclining push buttons required two people to do it. Overall experience was below standard. The same food was served both the times. No snacks in the ally, drink choices very limited. It felt like it was the year 2000. The crew unfriendly, hospitality 4/10.

Friendly on board crew, kept informed on flight. Pre-ordered food arrived as ordered

Old tired plane, Uncomfortable business class seat. Breakfast dreadful and meagre. At least flight was on time!

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

I would like to recognize a crewmember for her above and beyond service. Her name is Emily Milburn. The flight was delayed for more than a couple of hours, as we sat on the tarmac because of a storm in London. I could not connect to the Wi-Fi, which I needed to do to arrange for my follow up flight back to the US. This young lady told me that her cell phone had reception and offered to provide me connection through her phone. I was beyond impressed. Later on the gentleman sitting next to me, could not connect to the charging portal. Emily came back with her personal auxiliary battery and offered to the other passenger. She certainly needs to be recognized by British Airways for going above and beyond what is expected. She was the ultimate professional and very friendly, and I have to admit that, given the delay, the passengers were not the easiest to deal with.

Both the flight from/to San Diego and London went very well. There were lots of movies from which to choose for entertainment, the food was nice, and the flight departure and landing times were good to minimize jet lag.

They damaged my check in bag and when I filled complaint they gave some minimal amount which is not even sufficient to buy new bag. Vey unhappy with this experience.
