Upset about cancel to St. John’s and no overnight accomodation

Upset about cancel to St. John’s and no overnight accomodation

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Entertainment kept turning itself off. Gave up on watching a movie.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not United Airlines' fault. It's ORL airport's fault.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

Boarding was delayed 50 minutes. The flight going to Chicago was canceled, causing lots of problems and causing me to rebook and miss an event. I was traveling with a colleague, and he was unable to get on the same flight after 40 minutes on the phone, which meant I had to wait for him after my arrival. My flight down was delayed an hour before take off, had to sit on the plane, then 30 minutes after landing to get to a gate. No real food, only juice/ water offered for the 3.5 hours on the plane. Not a good experience.

Check-in was a nightmare. Wouldn’t let us board with our dog even though he has flown on anir Canada before. Only one of us could go. Will never fly them again.

Flight got cancelled and didn't get another flight til late and almost missed the connection because so close. We are still waiting for the bags to arrive the next day.

Overpriced. Exploitative price gouging. Appreciated getting bumped up to a seat with more leg room though.

Announcements were unintelligible. Entertainment system was non-existent. Ground crew kept changing story for flight delay.

After waiting for hours of delays, the flight was canceled. We missed our flight to Iceland from Toronto. We tried for hours to get a reasonable replacement flight, but it was the next day before we could even schedule another flight days later. We had to cancel our anniversary trip because we could not get to Iceland on time to keep our reservations. We won’t be flying Air Canada again as they just don’t have the infrastructure to deal with cancellations.

The only problem that I have is if you have questions about your flight ✈️ there's no one to communicate with when you call 📱.

As seems to happen every flight from Toronto to Ottawa we were delayed twice. We try to avoid Toronto when possible.. Denver to Toronto was fine.

Amazing and light experience, boarding on time, crew is super nice, clean salon and special thanks for movies availability. Provided by United Airlines

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

The first flight was delayed by an hour and a half, so we missed the second flight. They rebooked us on the later flight and I have to sit in the middle for more than 5 hours. Terrible experience. No more American Airlines.

Flight was fine, but not having WiFi was a major negative

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.
