On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

For some reason there was a change in the cockpit which delayed us by an hour

flight changed by airline. then could not check imto mew flight because kiwi had messed up the reservation. still waiting to depart…

Good. Really crowded and busy. Going to Winnipeg plane was crowded and seats very narrow Now I remember why I dislike flying 😈

Having a lot of delayed flights on West Jet, however things always work out. So no complaints.

Check in was seamless , crew very polite , arrived on time!

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Seats can use more cushioning, it felt very hard. The snack option could be better

Over all good. I had some issues with trying to buy my seat. The Westjet system kept trying to charge my credit card, without getting the seat. In the end after 5 times being charged, I got my seat.

I did not have a meal or entertainment, but flight was comfortable, beverage service was quick, crew was very helpful and pleasant. And a very smooth flight overall.

WestJet does make an effort to make the flying experience enjoyable. While I could have saved some money by choosing a different airline; I was able to fly directly, and with minimal hold-over. The extra $150 was well worth it

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

my seat got changed twice after checking on then boarding it had been given to a family so by the time they found a seat for me no overhead storage left. i ended up losing my Sony Headphones case because i could even access underthe seat in front of my when deplaning.

All good, useful to have the united app from check in to boarding

All planes flying to Mexico City are very old. Seats don’t even have power outlets.

It was spectacular. I had basic Economy and was given so much space and their seats lean back so far. Staff was superb, food was superb, everything was superb, Finnair is Fantastic.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

Very bad experience, probably will never use this airline again unless I have too. In the airport in Chicago made us buy a return ticket otherwise would not let us fly to Belize and stated that the Belizean Immigration will not allow Americans to come in without a return ticket or a Belizean supervising the travelers which turn out to be untrue. The staff were very rude and unprofessional and we almost lost our flight until the supervisor who was Hispanic and we spoke with him in Spanish and helped us and still had to buy an expensive round trip ticket. This was a very bad experience and we made a mistake by booking with Air Canada, usually using the AA and never had this issue.

Tout était bien, comme pour la plupart des compagnies aériennes, le seul bémol était leurs système de divertissement qui a cessé de fonctionner en plein milieu du vol. Un peu décevant surtout quand il reste encore 2h de vol.

Affordable & comfortable. Not sure why a party of two I booked at the same time got seated separately.

Everything was great with the Air Canada portion of the flight. However it was a co-share flight & United Airlines on my return trip. For my return flight I did not receive ANY correspondence at all from United airlines regarding my return flight. It was most disconcerting, especially as a senior, as I was unable to check in the day before the flight, could not book my seat & as a disabled senior ended up in the very last row of a fully packed plane. Service was abysmal & there was no in flight entertainment.

I did not like the heavy traffic to fly out of O'Hare. I had troubles checking-in. United app refused to accept my passport so I had to check-in at the airport. I had to check a bag but United could not read my credit card, so I had to buy a Visa debit card to pay for the luggage. It costed me an additional $6,00

Pretty much as good as an economy flight experience can get

45 minute delay take off. Entertainment system froze half through the flight.

Could not hear the announcements at the gate when boarding. Not loud enough.

Super Friendly staff! Airport boarding was a bit confusing as they didn’t really make it clear what zones were boarding.

The crew was friendly and good and I felt safe and secure in the air. I was not happy to find that my “window” seat had no window, when I had options at the time of check-in and would have selected another had I known. I felt a bit claustrophobic. I was also unhappy to pay $75cdn to check my bag, to then have it go missing for 1hr 20mins, upon arrival. I could have been half way to Oxford, my final destination, in that time. The dinner was good, but the breakfast is quite terrible now. It is two sugary items and only one coffee service in an increasingly small cup. We all know inflation is a big thing right now, but skimping on tea and coffee!
