No pilots so we were two hours late taking off and then no gate agents when we arrived in Salt Lake.

No pilots so we were two hours late taking off and then no gate agents when we arrived in Salt Lake.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Terrible last row seats many seats available but no offer to move to better seat

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Extremely bad BAD BAD BAD. NEVER TURKISH AIRLINES EVER AGAIN..PIRATES COMPANY.

Typically great service from Turkish with comfortable seat and amenitie, good food and great attention from staff.

Delicious food, comfortable and clean plane. It's a little cramped in the hall in front of the gate.

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The crew on this flight provided exceptional business class service to me.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

They oversold the tickets by one which was my ticket so I didn’t have a ticket till last second

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

Everything could have been better. What needed to be wrong with United went wrong

Excellent service. The crew goes above their way to make the customer comfortable.

It was good. The seats in economy weren’t bad

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Excellent service; they helped me reschedule so I can fly in an earlier flight

Wonderful staff. The boarding process can be improved a little better by adequate prior communication but all in all they did fine. However the boarding gate was quite unfreindly to elderly and who needs help with sevral stairs.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

Very good. Comfortable and I felt well taken care of from start to finish

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

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.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!
