Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Too many boarding protocols. Never experienced with other international flights.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

Crew on this flight was terrible. Especially one practicular female , she was harassing us and other families with children. Flight was good overall, if not her being rude and aggressive

Istanbul to Miami Sector the plane was nice and clean except for no WiFi during the entire flight. The flight from Karachi to Istanbul was another story .The sad part is we paid for business class to be comfortable. The foot rest didn’t work. The flight attendant had to push the seat to put to recline position and/or put it back. This was not only for me but for other passengers in business class. The tray table would not come out so had to get help from the passenger sitting next to me. I understand that they may have to use old planes but Turkish Airlines have to make sure that the things are functional especially the duration of flight is six hours and they are charging a lot of money. It seemed that i was flying a domestic sector instead of an international flight.

A very good airlines; we were pleasantly surprised by the attentive professional and service! Great job.

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 are better cushioned then some

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

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

My concern is with Flight: 441 IAH-FRA I was very cramped in my seat and the person in front of me was reclined. I pulled my wallet out of my purse and when finished I did my best to cram it back into my purse. Our flight was very delayed and we were rebooked twice and lots of airport time. As I got off the flight I noticed that I had dropped my wallet( containing all my credit & debit bank cards + 240 US dollars & 240 Euros. I spoke to customer service & Lost &Found. I was denied access to look on the plane. Therefore I have been without money and given no help. Paula Bjork 503.545.6698

So far so good. I missed my flight because of the Lufthansa diversion. United helped me to figure out how to get accommodations from Lufthansa for my long layover. They help me book appropriate onward flight.

During the flight there was a medical emergency. We were diverted. Of course I'm thankful they cared for the health of that passenger, but they did a poor job of communicating with the rest of us passengers. In the end we arrived at our destination several hours late, with no direction of how to rebook missed connecting flights. It all worked out in the end. Those of us that needed accommodations were put up in a hotel by Lufthansa until we could make it to our final destination. But it was United Airlines Personnel who really helped us navigate the process.

Always a pleasure to deal with United's helpful and knowledgeable staff

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Good flight. Take off a little late but make up the time

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

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

Great flight and reminded that the logistics completely Astoria. No real story about victors, m

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

You get what you pay for with RyanAir. This was a €60 round trip from Stockholm and every piece of it was just excruciating, from the plane being delayed by more than an hour, to having to stand out on the tarmac in the darkness at 3C and wind to wait for the plane to disembark its previous flight (why they do this is just cruel), to the crew keeping the lights on the entire flight despite it being so late so they could walk through the aisles and try to sell things. I always say “never again!” after flying RyanAir, but somehow end up getting lured by the prices…

Largas colas para el check-in, por seguridad, sin explicación, el equipaje de mano pequeño tuvo que pasar a bodega,

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late
