Crew was friendly Love the entertainment in the seat head rest.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

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

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 !

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

It was terrible, if they ran flights on time it would make a big difference.

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

Any sort of gluten free snack option would be nice

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Crew professional. Easy bag drop off. On time. Good entertainment.

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

The flight was on time and everything went very smoothly.

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

The best thing about AA is that the onboard entertainment allows me to watch on my iPad. This was not working. USB ports were not working and the flight attendant said they often don’t work. The flight attendants, one in particular, were uncaring. I was very disappointed.

My husband required a wheelchair to get to the airplane and the service he received was exemplary. Thank you.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

crew was great, wifi was very poor could not even load a youtube video

WestJet was able to re-book us to the next available flight at no charge when air traffic controller staffing shortage delayed our inbound flight

Our flight was delayed for almost 2 hours resulting in a rush to connect to our next flight

I am a tall woman and could not move my legs enough to reach down under the seat in front of me to retrieve anything I put down there. I sat in both aisle and window seats and felt extremely cramped. In the aisle seat, if the stewardess was heavy, it was impossible to pass, and she would knock my arm shoulder and thigh every time she went by. If I can avoid it, I will not be flying this airline again.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Get our, as a group, skis on time to their destination. Have more attendants checking people in. There was only one. The line was a block long :( . Also flight change with 5-hour delay

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

My experience was poor with customer Services. Please consider flexibility with cancellation due to emergency health condition. Thank you.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Disappointed my flight was delayed to TO as i had a connection to make. Ran through the airport I made my flight but I initially had 1.5 hours to connect. Unnecessary stress!

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Delayed delayed delayed cancelled and all we got was $60 food or beverage Embarrassing I'd say

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.
