Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

Flight was delayed and we were on the runway after landing for 30 mins

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.

The morning calzone was less than impressive and we ended up with heartburn

It was good delayed again but once on board the flight crew were very good the entertainment and wifi worked on this plane and we were offered snacks and drinks

The second half of terminal C at Hartsfield was 80 something degrees. I was sweating just sitting at the gate.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Did not get a vegetarian option in 1st class and the video was not working.

I did bought anything… I don’t understand how this book appears to me . Ridiculous

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

We got delayed to the point of having a 20 hour layover. That is absurd. I couldn’t believe it. I’m furious.

Delayed boarding. Delayed taking off. Delayed landing. Missed our connecting flight. Our seats on this plane were not assigned until last minute, splitting up our family with kids. I sat in the last row next to the bathroom with so many people rubbing up against me to get to the bathroom the entire flight.

Another delayed flight. Then got bumped to a later connecting flight, over two hours later! Plane was hot and uncomfortable.

Crew was nice especially by North American standards. Bad good. No entertainment screens. Terrible WiFi

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

no staff available to help, no systems available to coordinate

The additional charge for the WiFi was not worth it. Streaming a football game was a joke as it continued to lag will be requesting a refund

See review from the other leg San Antonio to Atlanta.. basically the same experience as the flight was operated by Delta.

Flight late …60 minutes No food No wifi No entertainment system A disaster!!!

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Crew was rushed to get food out and left trash for a long time on our tables.

The entire aircraft was outfitted with comfortable business-class seats that featured luxurious reclining capabilities and built-in footrests for added relaxation during the flight.

Getting on the flight we booked would’ve been nice to begin with. Nope, they cancelled the 10 am flight. Herded everyone on to the 5 pm flight which got delayed twice. Basically made it to our hotel at 11 pm. So we lost our entire day in Toronto. Paid around $500 Canadian dollars to spend the night in downtown!! While they save a boat load of cash herding everyone on to the 2 evening flights.

Air Canada cancelled our flight the night before and rescheduled us for a flight 32 hours later than our initial flight. That would have made us miss our events in St. Johns and throw off the rest of our weeks plans. We cancelled our flights and the entire week in Newfoundland. Also want a complete refund not a credit.

It was very small. Just plain ride for a few hours, that is all.

Like most Air Canada (AC) flights, it was delayed. And in this case, there were luggage problems. Somehow someone else's luggage got assigned to my ticket so that created some confusion but was easy to resolve and I ended up having a nice visit with the people who's luggage was attached to my ticket. This is touchy subject for me as AC has lost my luggage many times (or the airport, I'm just not certain who to point at as I don't know) In flight was pretty standard, one lady was wonderful and the rest seemed mediocre in comparison. We landed in Toronto and had to wait on our gate, then pulled into our gate and spent an additional 30 minutes waiting for a ramp to get off the plane. I don't know who was at fault here, Pearson's horrible organization and terrible management or if AC didn't plan to have it there. To do better, more attention in the bag drop process would be good. Then hold the airport accountable for the lost luggage (I'm looking at you Pearson from the time you sent my domestic flight luggage to Turkey).

Boarding was good. No snacks was a bummer and crew did not take up trash. When asked twice about ear plugs for movie no one came back with any. Nice to have movies offered free however if you aren’t able to listen to them not very good.

it was great, a little chilly on the flight but that’s fine since i had a sweatshirt
