The WiFi was not working. That made for a long flight.

Flight was delayed due to crew being not on time

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

Timing, quality of service, promptness and courtesy of the staff

It would have been better if the flight wasn't delayed by 2.5 hours

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

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

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Lisa the flight attendent was absolutely wonderful - I loved her energy and you could tell that this crew was amazing family - thank you for making our flight home to LA so very fun! Love and Sun Chips!

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

one of the flight attendants on the Dallas to frankfurt leg was somewhat rude..

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

A little bit more leg room in premium economy. I am 6’4”.

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

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Food wasn’t very good, old business seating configuration on an old A340

Crew is way too many times on the intercom re explaining the same thing

Nothing. I flew business class. I always try to avoid air Canada because it’s the worst airline and it’s proven on international level. Sad and embarrassing…
