The ground transportation situation (Uber, taxis) at International Arrivals (Terminals D/E) is frankly pathetic for a major American city. Way too many people and cars for the allotted space. I would recommend taking the mini-train to another terminal (A,B or C) and getting an Uber there, rather than trying to navigate International.

The layover period at Frankfurt of one hour and forty minutes was not enough time to clear the two-hour line at passport control: we missed the flight to San Francisco. Condor did a good job rebooking us that same day, but our bags ended up in Los Angeles.

The layover period at Frankfurt of one hour and forty minutes was not enough time to clear the two-hour line at passport control: we missed the flight to San Francisco. Condor did a good job rebooking us that same day, but our bags ended up in Los Angeles.

This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Boarding by bus - this is 2026! Luggage did not board the plane though we had over two hours between flights. After it was located it didn’t fly immediately but waited one or two flights until boarding to fly yo Belgrade.

Accommodate the passangers at the gates. They only allow groups 1-3 to sit near/at the gate. We had to wait 3 HRs an had to look for a seat far away from the gate. Other than that was like other Airports.

It was a great experience. The aircraft is a bit dated but other than that it was great.

Last few years I didn't not have great experience with United Airlines.

Booked economy. Seat felt like it was a bit more roomy than my last trans Atlantic flights. I had a nice person sitting next to me. Everything was as good as it could be considering you are 35,000 feet up in the air and in a metal container. Beers, wine, food were all readily available. Plenty of movies and shows to watch. Friendly flight staff

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.

My Austrian Air flight from Montenegro to Vienna was delayed by three hours because their plane de-icer was broken and they had to wait for the sun to come up before the ice could melt. This meant we missed our United flight altogether. So I can't speak about United, but I was not impressed by Austrian Air. They made us check in two carry on bags for a 60% full flight, and the bags didn't find us in the US for ten days. The re-routing they arranged included an extra leg, a midnight taxi ride across New Jersey and New York, and a five hour sleep in a hotel. Not impressed.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

The flight to Houston the agents were not very helpful

Horrible, absolutely horrible. The airline overbooked the flight, did NOT assign seats and boarding was a hot mess with lots of confused passengers. There was no "large plane" gate for us, the 500+ passengers were squeezed in a small hold room area, and multiple busses had to shuttle us to the other side of the airfield, where boarding of the plane, that was parked on the ramp, took place in rain. The old plane had a broken seat, that the technicians tried to fix - with no success - resulting in a 50min delay. The flight attendant with heart shaped earnings with German flag was screaming on the passengers without a reason, was extremely rude and entitled the entire flight. The food was junk. I hope I don't have to fly United ever again.

No screens or meal options. Freezing cold. Dirty seats. Left late.

It was terrible. sat on airplane 2 hours then flight was canceled. made to pick up bags and go through Panama immagration to rebook another flight. worst experice ever at a airport.

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations

First time flying with UA and it was a great experience. Thank you

The gate attendant in Boston had a high raspy voice and spoke much too fast to be understood. Not pleasant.

The flight was delayed for more than 3 hours the flight attendant was so angry, it was my first flight with JetBlue but i don’t think I flight with them again.

Since we started at syr the service, crews, and flights were just excellent

It was fine for what it was. It’s not luxury travel but it was efficient, for the most part. Having my carry-on transferred into luggage however, was unwelcome.

Jet blue is always good - the one weird thing was that they started boarding about 20-30 minutes before the official boarding time on the app. Just something to be aware of!

We had better-than-average leg room and I loved the access to shows and movies. During boarding, we could not hear the agent even though we were close to the boarding door, which was kind of scary when we realized that half of the passengers had already boarded. Also, the entertainment was awesome, but I could not hear the movie as well as I would have liked, because my headphones were crappy. It would have been better if I could connect my own ear buds via Bluetooth or if JetBlue provided headphones.

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight did not have onboard charging and TV screen flickering.

I was seated next to an autistic child who was out of control and had a child behind me kicking my seat for most of the trip. I will never fly JetBlue again. Ever. I don't care how cheap it is. It's terrible.

Boarding process was terrible. No assigned seat until the gate, then a long line to get seat assignment.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

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.

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.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

The plane was late (as was my flight out from Birmingham the day before)

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.
