We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

Terrible. They wouldn't allow me on my flight on the 14th..

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

The best airline for international travel in terms of value you get in business class (service/cost)

On the Boeing 777-300 aircraft there is no personalized climate control for passengers. Every time I've ever flown on this type of airplane I've been uncomfortably warm. For shorter flights (less than 5 hours) this isn't a big deal, but on longer flights where a nap is required to stay comfortable it turns into a nightmare. I love turkish airlines, but I really fo hope they upgrade their fleet. I've flown turkish air once on a newer model and had a fantastic time, so I think its the plane more than the airline.

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

It was good..clean, comfy seat. Friendly warm welcoming crew. Was able to check my cabin luggage at the gate which I was able to pickup in a decent time from baggage claim. The app gave all updates from delays to baggage claim info. Overall smooth flight.

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

We are too tired and frustrated to comment politely at this point

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

The flight was flawless and we even arrived between 20 and 25 minutes early!

The only thing to like was that we eventually got to our destination

Delayed delayed delayed and no offer for food or vouchers

The seat space seemed small especially when the person ahead reclined but other than that, very good.

The crew on my Frankfurt to Chicago flight were outstanding!! Friendly, helpful and worth taking the time to write an excellent review on their behalf. I would fly Lufthansa again just because of their warmth, kindness and humor!

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

in athens they helped me with my dogs and they solved all my issues excellent service outstanding

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

We would have missed our connection from Munich to Boston but we had a van outside the plan that wisked us to our terminal. Much appreciated and we didn’t even realize that Lufthansa had done this until the announcement on disembarkation. Well organized airline! Will definitely fly Lufthansa again!!!

Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights

Bought a seat in a flight that got changed out so ended up paying for a seat I would have had if I hadn't paid.

Food was poor quality and the screens for entertainment didn’t work properly

Food was much better than my outbound flight. On-time. Good service. I had a problem with my entertainment screen, but the attendant fixed it promptly.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.
