Should never have had to go to Detroit from Orlando back to Tennessee!

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

Boarding was good. The flight was on time ( arrival was 20 minutes early). Inflight service was average ( US airlines have not mastered the skills of customer service yet). The food was mediocre. “ breakfast “ was downright awful and insulting. It was a piece of dough with mon descript filling that was supposed to be cheese omelette).

Miserable. This entire round trip was miserable. I booked evening flights to and from Detroit on consecutive days that should have had me at my destination by 10:30. Instead I arrived after 3am on my flight to Detroit and after midnight on my return. Multiple unforced errors like awaiting bags to get put on the plane for almost an hour in Detroit and a 20 minute delay to pull up to the gate in Atlanta has me rethinking my assumption that delta is the best and most reliable airline

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

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

I have flown Qantas multiple times in the past it seemed this flight the plane had less seat room or the seats were way less comfortable than before. Everything else was about the same. Thanks

I disliked the fact that they forced people to put up their seats during meal service

Headphone jacks worked poorly, seat recline was broken. Planes were rundown.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

This flight is a quick way to get to Chicago, but a bit expensive.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

Staff friendly and app worked really well. Modest delays were frustrating

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

It was a good trip. Flight Attendants were friendly and responsive.

They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.

The trip was very smooth and they provided great customer service

Everything was excellent. I loved my flight Thank you so much 😊

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

It was a crazy day with a lot of delays and gate changes. Not a huge fan of the Charlotte hub at all.

We have been delayed and postponed 2days and nights…and still do not have our flight until tomorrow..

American Airlines is awful!! Will never fly with them again. Connection flight left early leaving 22 people in Charlotte with no way to get to Key West for 24 hours. Would not provide hotel or any other accommodations. Bags were delayed two days.

The flight was comfortable and the staff were helpful and friendly. However, we did not know we were flying PAL until we arrived in Canada, so it was a bit disconcerting. In addition, which port we were leaving from was confusing.

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

It was a small plane and difficult to put my carry-on bag in the overhead compartment. The crew was awesome and boarding was good.

Both legs of my flight were delayed and my luggage did not arrive at my destination. It was a very frustrating experience.

Flight from Toronto to Calgary was >2 hours late departing and was overbooked

The plane was two hours late and we got bumped. Instead of getting to our cruise ship at 10:30am it was 09:30pm. We also got bumped to Edmonton instead of Vancouver.

I like the friendliness of the crew. It could have been better being more on time. The flight from Detroit to Toronto was delayed two hours.

Flight was delayed enough to miss my connecting flight in Montréal. The Quality Inn was not quality. The ”dinner” at the Quality Inn was sugar heavy drinks and dessert and a cold cut lunch wrap. Not a good experience.

One flight was cancelled and air Canada rebooked new flight immediately for me. Checkin was awful at Detroit metro airport. No clear signage, I was directed to wrong line and found out after 15 minutes of waiting. Air Canada line was extremely long with limited checkin counters moving very slowly.
