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

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

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

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.

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.

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

I like how professional, fast and good the whole experience was.

Nothing special.. they could have provided something to eat without a charge

For the price of the ticket it's probably the best service in the world

Seats are too cramped, but that is a problem with every airline. I actually enjoyed the meal served.

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

I have no complaints. The crew was attentive, pleasant and heloful

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

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.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

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.

Courteous and warm. Good experience while traveling back with an infant.

I liked BA land team for boarding, the food, entertainment should be considered to be improved

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.

Reasonably comfortable. Plenty of room. Crew were attentive and continually informing passengers of position. Although stuck in runway for 1 hour, weather issues, it felt like we were the crews first priority

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 .
