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.

Delta is a premier airline so my expectations are most always met.

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 !

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.

Good and consistent Printer in lounge did not work for me :(

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.

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.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

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.

It was great! Boarding and taking off on time, good crew—thank you!

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.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

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.

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!!!

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

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.

Air Canada business class used to be among the best among North American airlines, however it has gone downhill since the last time I flew with them. They didn't even offer any drinks prior to takeoff despite having over 30 minutes on the ground for boarding and de-icing. Once we got in the air the service was fine, however the food was lukewarm at best and just okay. The warm bread and spring mix salad was very good at least. My main complaint is they were letting economy guests use our washroom. Presumably because the Max 8 only has one in the rear. However as I was sitting in row 1 I constantly had passengers waiting in line for the toilet.

Very smooth flight and the crew members were very welcoming.
