Airline reviews

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

2+hrs delay without any reason provided and a cramped flight

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Good but need to be better with the flight times.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

If you want your flight to get delayed constantly for 13+ hours and given a 10 dollar food voucher the. I would say take air canada. Worst experience ever.

The idea of needing to go outside in the winter to board in icy cold temperatures is totally a non starter for me. Seats were very uncomfortable though the leg room not too terrible. Attendants were nice

Gate changed twice, boarding late. However, there was more than usual leg room. Crew was fine. No entertainment due to computer problem.

Our flight was delayed by almost 1 hour, and this negatively impacted our experience. Everything else was OK.

I was treated poorly after contacting customer service, including invasive security enhancements and being waitlisted suddenly for a flight I’d bought over a month prior. I interpret this treatment as intentional.

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.
