No delays, helpful staff, well organised. The check in and boarding procedures ran smoothly. The only thing that put me off is that the meal had spicy peppers in. I would have appreciated at least a warning (if i couldn't have a choice) so as to simply not eat them because they were too spicy.

No delays, helpful staff, well organised. The check in and boarding procedures ran smoothly. The only thing that put me off is that the meal had spicy peppers in. I would have appreciated at least a warning (if i couldn't have a choice) so as to simply not eat them because they were too spicy.

Schedule and on time departure and arrival were great. The crew was good, but a change in aircraft bumped many of us from our expected seats. It was a crowded flight, but the cabin crew did their best to keep things under control.

The crew was attentive but not intrusive, and was always kind in every interaction.

Austrian was not the issue. Kayak was terrible The flight was canceled. Frustrating but it can happen. The worst was Kayak's customer support around re-booking. I have chatted with a bot, than with a person who insisted the flight was still on as originally booked. while chatting i went on Austrian web page and told the kayak chat lady that the flight is shown as cancelled. She said she will escalate this and that someone will contact me within the hour. When I have asked her to give me the details of the flight she sees, She gave me the general A to B and return B to A. Totally unhelpful. After two hours I contacted them again, They were still saying the original flight is as scheduled and when I explained again I was told I will be contacted within 2-6 hours. NO ONE CONTACTED ME EVER SINCE! I have than contacted Austrian directly and was rebooked on a difficult flight. Kayak continued to send me irrelevant updates about my original flight. Terrible customer service at time of need.

Austrian airline they cancel my fight , and the couldn’t give me flight , they said only available flight 4th and after , I sacked for refund, even from you KYAK , and tell now no any refund , because what happened I lost more money because I have to stay in hotel and then I buy new ticket

the flight was canceled, and I had to stay more than six days at hotel . waiting . then I had to buy new ticket. really it was very bad experience, and I lost a lot of money and time , and your airline said sorry

Management and staff att viena wasn’t professional,and they are not good by how to communicate and solve the problem, I was shocked , as I know Austrian airlines was amusing Thank you

The baggage arrived damaged and i spent EUR 300 on the baggage a month ago. No responsibility from airline or the handles.

Tight connection from Austrian Airlines made this challenging. Our luggage did not make it, delivered the next day at noon. Flight itself was very full, not especially comfortable.

The flight was late. We accommodated other missed flights, and the plane was full of people, without space to store carry-on luggage. They lost our checked luggage for the entire flight and delivered it after two days.

Great service, great food, and comfortable business class seats... Friendly and professional flight attendants and ground crew, overall 5 star experience!

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

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.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Flight was late due to mechanical, had to spend night in hotel. Experience disembarking plane was poor, United did little for passengers except what they were required to do by law.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.

The trip was good except for the delay that caused a connection issue in Chicago.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

The flight was wondering, especially the special assistance from airplane to airplane!

The flight was wonderful, especially the special assistance from airplane to airplane!

They canceled our flight last minute and we had to get another flight with twice the cost

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

The worst experience of my life and I have been flying for 33 years

We were very upset when we checked in for our flight to be charged 208,00 euro for luggage fees when the site clearly states we are authorized one checked bag each and one carry-on. We have never experienced anything like this with Lufthansa and are very disappointed. We should be reimbursed this erroneous charge. I can forward all receipts once I am able to scan the them.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

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.
