A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Food choices were very limited. Taste of the dishes was average.

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Sucks ! All three flights I was on this trip were delayed.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

We were delayed Al ost / hours after boarding so that maintenance had to add oil to the engines. Then the oil they grabbed had been left out in the Dallas record cold and was frozen. They had to go back to the hanger and grab some that was not frozen.

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

Everything was on time, we arrived early, everything worked well.

Angela was the best fa ever. She made that 8 hour flight a breeze

This was a pleasant, short flight and the crew was friendly.

The service and food needs to improve to catch up with other international flights

Small plane, so no entertainment. Hour delay! Nobody explained wht the delay was all about.

Same problems with delays in Dallas. This was weather related and due to the incoming flight being delayed. This was the flight that was delayed due to a missing flashlight which turned out not to be missing.

The flight was on time. The seats are very narrow.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Seats are poor. They do not lean back. They do not even have pockets on the back, making it impossible to store a phone or a coke bottle. If you opt for basic economy cheap seats, they stick you always in the middle or window seat, even though there are unoccupied seats on the aisle. And then there is the nickel and diming. No carry-ons. And checking your carry-on is $70. At the end there is no price advantage but there is plenty of aggravation.

Flight crew was great. Spirit leaves a lot to be desired in terms of comfort.

Worst Airplane ride I ever have taken... My purchased seat was changed without my consent

would be great to get basic water, soda at least and stop charging for carry ons

They changed our departure time 6 times before I even reached the airport. Delayed, Ontime, Delayed Back on time, Then Delayed. We finally boarded the plane and then we had to sit on the runway for over an hour only to be told they were taking us back to the gate for an additional 2 hour delay. Lack of communication and a complete waste of time! Never again!

Very difficult. Flew out on Dec 24th and it was a mess. They know it is going to be the busiest time of the year and they had no organization. Finally they called for people going on certiam flights so they could get them thru thw line then we had to rush to our gate to get in li e to board.We missed our flight do to being stuck at the border of Mexico. They would not work with us to make an affordable price so we had to wait a day with no where to go and pay 280 more for our flights. I would think that a complimentary drink would be nice. But we had to pay 4.49 for a coke. Not an overall good experience

I couldn't understand the crew when they announced it was a new plane and there was therefore no wifi, huh? Seriously lame for 2025!

I did not fly Spirit. Connie fraudulently used my email to book her flight. I do not know Connie!
