Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

More extra space was awesome. Even though I was on the first groups to board, bin compartments were already occupied by passengers seated on other seat numbers. That is unacceptable.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

All good on Delta's part. Passengers could be a little more courteous to each other.

Screen didn’t play movies, do I was pretty boated the entire flight.

Inconsiderate staff, plane was very hot, poor decision-making from the crew.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

Flight was 3 hours late so only had an OK experience

Food was horrible! Inedible sandwiches by a supposed star chef, Assaf Granit. I was dead hungry the entire flight but couldn't possibly stuff that awful sandwich down my throat,

El AL has vastly improved its overall experince in the last several years. Nicer place, nicer flight attendants, food, comfort etc

The food is horrible!! The staff not smiling and looks that they don’t want to work

Remind me not to fly (eat) at passover with Israeli cartiers. Came out of the aircraft with an incredible neck pain. Crew and entertainment were good.

Great entertainment system. The crew was somewhat helpful, but ignored the calls completely. Also all the isle seats were taken by the time of check-in and we had to squeeze a family of 5 on middle seats in 3 rows - awfully inconvenient to fetch nappies, take kids to the toilet or fetch water. Seat spacing was ok and the missile defence system of ElAl planes is unmatched.

Window seats on the 737 are tight and narrow. Staff was good.

the luggage was delayed to the point i missed my next flight hich was an hour after arrival not good at all

El al is the best choice for flights to Israel.

Delayed as always, very dirty and old airplane. Not very friendly staff. Just a sandwich for a 5 hours very expensive flight.

The crew was great, the seats were comfortable, food was a sandwich , but very tasty and the ElAl new on board through WIFI was good. Thank you EL AL for improving

Flight was late over a hour just like the first one. WiFi was down.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Generally good. The crew is excellent. The food could be better.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

They charge me for luggage which is was included on the ticket

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

Business class in the second leg - CDG-EVN was a disaster.

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

3.5 hour delay known 12-16 hours before departure $15 meal vouchers which did not even cover cost of sandwich. Unable to reach agent for 1.5 hours, only then to be informed any rerouting to my destination would cost an additional $1000. Finally got rebooked on a 7.5 layover in Denver only to find out my original connecting flight was also delayed so I stood by and got on my original connection arriving only 3 hours late instead of 5 hours late. Overall journey was unnecessarily stressful and lenngthy!

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

We love United Premium Plus! So comfortable without the cost of Polaris Club. The crew was so attentive and friendly!!

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.

I have to wait for plane in Denver for three hours. I don’t receive my luggage in Denver. I come back home without the luggage and I wait till next day to see my luggage again. Not really good experience with United airlines. I’m sorry to say that.

The Wi-Fi was unavailable on this flight for some reason.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

Boarding process was hectic and unorganized. Delayed for hours, THEN delayed for weather.

No complains with the crew. But generally speaking food is awful, entertainment is not good either.

Very bad flights I lost my luggage for both sides

It departed late from Frankfurt. It was diverted to Toronto because of the storm. Stayed in the plane for 4 hours hoping to make it back to Newark on the same aircraft. After finally getting off the plane, it took another six hours at the airport to get the luggage and get a hotel room nearby. Still don’t know when I am flying back to my destination.

After a bad experience of traveling with United airlines long time ago I decided to give them a second chance. And again it was bad. The flight from Jacksonville to Washington was almost 4 hours delayed. Due to that my flights to Munich and Warsaw had to be rescheduled. As a result I had to travel through Frankfurt. And my checked in luggage did not arrive from Frankfurt to Warsaw with me. Warsaw was not my final destination and I had to figure out a way to deliver my luggage to my destination. On top of everything my Delsey luggage got 2 cracks. Is anybody going to be responsible for that???

Staff was helpful. we left on time and arrived early to destination.

Food was excellent. Staff were very helpful when asked a question and followed up with an answer quickly.

It was disappointing that I could not sit next to my wife but I was not allowed to pick my seat

Flight delayed by an hour from the get go which almost cost us our connection which we only made by the grace of God.

Handling of baggage. We had a two hour delay and they still did not get baggage on flight
