Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

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 food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Most important was the effciency - on-time take-offs and landings, no missed connections, baggage arrived correctly. Friendly & professional crew. Less important was food/drink. Pretty spartan, but we'll know next time and bring our own stuff.

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

I thought Miami's airport was very disorganized during the Boarding.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

People seated in exit rows should have designated overhead space

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!

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

Flight was 2+ hrs late boarding. Delay updates were nonexistent. Boarding Gate change was by word of mouth.

The plane was modern and clean. TAP staff at the airport as well as the flight crew were professional, friendly, and helpful. Overall, a great experience.

The airline made last minute changes to our business class seats splitting our family of 4 with young children who had pre-booked a row of 4 seats. The seat was also dirty and sticky. Our pre-ordered child meals were also not available. :(

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

This was one of the best travel experiences we've ever had with Ryanair. The flight boarded on time in Dublin, departed on time, and arrived on time in Split, even though the flight was full. The aircraft was clean, and all members of the cabin crew were both friendly and efficient. Even our fellow passengers were well behaved! So top marks to all concerned!

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Everything went according to plan. Check in, boarding etc all were very efficient.

Left on time and arrived on time both ways, thank you

Ryanair is the worst airline in Europe and easily one of the worst in the planet

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Em relação a Ryanair, ter de ir ao check-in só para carimbar o cartão de embarque não foi muito fácil, são muito demorados, e atrasam a passagem do controlo de passaporte... E cheguei com 2 horas de antecedência

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

Full flight. Seat 8 F. I don't usually have the business class seat at the last row. Feel awkward for the stewardess crossing over the person sitting on aisle. Nothing to complain, especially, the airline stewardess really tried to accommodate such situation. It is just an awkward seat.

British Airways planes are too old verses other airlines, followed by luggage not turning up, with a customer service team unhelpful in trying to locate or send to hotel was appalling. 3 days without suitcases on a leg that flies 2 x daily.

Annoying customer pushing my seat did not make this pleasant.

Not enough trash pickups throughout the flight. Everything else was great.

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

I asked for a wheelchair. I have a back health condition. I had to walk a lot

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports
