Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

Reasonably comfortable. We were about an half an hour late. But no personal impact. Seats upfront have a good amount of recline, but do not lay down flat. Food and drink can be improved. There are no soft drinks available on the flights. Water, juices, and wines are provisioned.

Flight on time. Staff pleasant and responsive. Food could be much better. Snack before landing was a few dry crackers and a drink. Nothing else. There was a very lumited selection of beverages available on a 7 hour flight. No soft drinks, even in the front cabin.

Delayed departure of one hour and half, inflight entertainment NOT functioning. Plane did not crash and I arrived alive, so I guess it was a good flight.

This was a long flight - 6 hours - and nothing is truly comfortable for that long... but the flight crew was friendly and attentive. The airport in the Azores is small but we weren't there long enough to explore any amenities.

There is one flight a day and it was canceled with no explanation

Flight was ok. Food on way there great a pork dish way back tuna and pasta was not good. Flight attendants were great. Wish they had more soda options like ginger ale seltzer water. Good experience overall. Worst part of trip was car rental Klass company car broke down we were on side of road late night 4 hours awful awful experience all they wanted was 500 euros for help to come absolutely horrible experience we were scared side of highway they offered zero help!

Coming from USA it was nice to be treated nice for a change. Even though our flight was pretty short we were served breakfast. On time flight with very caring staff. Please teach American carriers how to treat people.

More space between seats and in bathroom. I don’t think there was any entertainment offered. If there was, I wasn’t aware.

Every meal/snack included something with ham/pork - even the cookies had "swine fat" (which we only knew because we thoroughly checked the ingredients). There were no vegetarian options, and we had not been given the option of pre-selecting a meal when purchasing our tickets or checking in. That made for a VERY long flight. We were fortunate that we had brought our own snacks as back-up.

Waited in line for hours just to get a boarding pass which would not print at the kiosk or load on my iPhone. Waiting again for about 45 minutes to get through passport control. Poorly managed airport. The flight and crew were great and the flight was very comfortable.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

I’m still missing my bags. I’m soo frustrated

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

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

Baggage check in was very slow. No sign that the check in was TAP until the station opened. Understaffed and overworked team.

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.

Our flight was canceled for a reason that suggests gross mismanagement. We were re-booked for a flight to a different airport.

Worst: long walk to baggage claim Best: left on time

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

Great overall experience with TAP - would not hesitate to recommend for your next trip to or from Portugal

Correct meal and overall flight went well. 204€ for an extra luggage is simply exaggerated

The seats were uncomfy and the food tasteless, crew clueless

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

The trip from Portland to Italy was great. However, the trip from Italy back to Portland was terrible. We started off leaving an hour late from Pisa to Heathrow, which then made it too late to reach our connecting flight. We were instructed by a flight attendant that we needed to go to "anyone of their colleagues" and we would need to change our connecting flight. Once we finally found someone from BA and stood in the long line of other passengers. Someone from BA came up to us while in line and asked if we were re-booking due to a delay coming into Heathrow. We told them we were, and she asked if we even checked to see if they already re-booked us. Nope, didn't know they would do that, so yes, they did in fact re-book us to a flight that would leave in 45 minutes, and we didn't have a boarding pass. "no problem just go through security and tell them you don't have a boarding pass" - It doesn't work that way. No one including security knew what to do. They kept sending us all over the place to people that didn't know what to do. Finally made it through security (after 30 minutes of everyone trying to figure out what to do with us). BA put us on a flight with Delta so we had to go to Delta to get our boarding pass. Flight was already closed, so Delta said "you need to go back to BA". Waited in line for 30 minutes due to only 2 people trying to help everyone. She got us out on a new flight that left the next day, with a connecting flight to Seattle. They put us up in a hotel that was obviously run down with a lot of passengers from BA. They told us to come down and get dinner - sent to a buffet and told we had to sit in the back of the restaurant. The buffet was not good. However, we hadn't eaten all day, so we were both starving. They had a vat of a meat sauce that said "chicken sauce". I started eating it (on tope of the rice they had) and just about chocked on a chicken bone and then found several other chicken bone slivers. The other dish said "chicken curry" tried that instead and there were whole large bay leaves that I didn't see (because it was dark in the back of the restaurant) and got one caught in my throat. Frozen mixed vegetables that said "fresh steamed vegetables" nope. Got to the airport early the next morning so we could make sure there were no issues. Flew out from Heathrow to Seattle (crew was great) landed in Seattle 20 minutes early, but couldn't get off the plane for 1/2 hour. Our connecting flight was in 2 hours. Got off the plane, and it took 1 1/2 hours to get our luggage. After 30 minutes, I went to BA's customer service desk to see if she could help. Her response was "it's not really my issue" after 3 passengers told her to make it her issue and find out what was going on, the luggage stared coming out. Needless to say, we missed the connecting flight again! BA had rebooked us with Alaska for our connecting flight. So glad they did, because Alaska was fantastic! The rebooking process was much easier and they made sure we got out of Seattle that day so we could get home. All in all, I will never fly British Airways again.

Business class to Istanbul. Packed flight. Cabin crew seemed incapable of differentiating between economy and business passengers with regard to access to the WC which meant whole flight I had people standing in aisle and leaning into my aisle seat, queueing for the front WC. Crew put it down to a lack of curtain between the two classes. The seats, for a 3hrs55 min flight were just standard seats with middle seat unoccupied. So nothing special apart from the food, which was mediocre. Aside from the roast chicken dinner (‘special’ traditional British menu option, which looked poor but tasted good I gather). However 2 king prawns does not make a main course salad.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

The Heathrow team was no prepared for the number of people who were coming through at that time of the morning, it seemed they were also experiencing shift change. The lines were incredibly long and moved at a snails pace. A airport rep walked by me, I presented my boarding pass to her and asked if she thought I would make the my flight If I stayed in the current lane. The look on her face told me I was not going to make my flight. She then whisked me to another lane, got me through the line and i ran to the gate and boarded my flight with only seconds to spare. It was a frustrating experience, which BA had nothing to do with. BUT after getting onto the airplane, the flight team was welcoming and I felt a huge sense of relief. Thank you to the BA flight team!!!

We didn’t flight with British Airways because the flight was cancelled at the last minute .

Service of the crews were great. Food on flight was very greasy, and salty.

Sardine can herringbone layout in business class. Uncomfortable and nowhere to put your book, phone, headphones, etc. worst hard product ever, and the service and food aren’t good enough to make it worthwhile. Expensive garbage. British Airways purchased this thinking only about financials, clearly not customer experience. British Airways business class is the garbage truck of the skies. Hard pass!

Staff member at boarding gate was rude, and more than once!
