The meal tray was not usable it was completely uneven

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

The flight was mostly smooth and direct (although it was 2 hours late). The glow of the flight attendant’s phone was annoying as I tried to sleep on this midnight flight.

Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

Crew was real good, flight was smooth and came in early.

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

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

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

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

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.

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

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour 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

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

I like the idea of a non-overnight flight to Europe.

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

I was very frustrated that our first flight from Grand Rapids to Detroit at 6.20AM was cancelled because the captain wasn’t legal to fly. Especially after the fact that we all had already boarded, then had to deplane. I was excited to fly to Korea for the first time with Korean Air for a connecting flight, but had to give that up because of Delta’s mistake. Not only that, but I wasn’t even able to sit with my dad on the longer flight. Our first flight after being changed was also delayed because the captain had to take an uber. The only compensation we got from this giant mess was a $12 airport expense voucher that I didn’t even get to use since we didn’t have enough time between connecting flights.

We didn’t make the flight due to Delta’s check in line moving too slow.

Flight was delayed four hours! No on board entertainment fir a four flight. Minimal food

20+imite delay on the plane with no air. Part of our group had no seats assigned and took a long time to get fixed. Again no wifi and snacks were sad

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.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

On board Entertainment and crew services were absolutely trash! Neither me, nor any of my 40 family/friends members are flying Lufthansa again!

Plane was delayed for over 1 hour causing us to miss a connecting flight in Munich. We spent 10 hours waiting for the alternate flight which was delayed about 45 minutes. We had a service attendant who was very helpful with our missed flight. Later in the evening when consulting service attendant, he basically said, the plane will show when it shows!

Food should be provided according to the passengers selection. In flight entertainment system must be updated with latest devices and applications. Proper over head headset must be provided rather than providing cheaper ones.

Very organized check in and boarding experience. Good crew very helpfull.

Deplaning at Frankfurt required ck=limbing steep stairs with no provision for escalator or elevator.

Flight comfort was good. However, due to delayed flight, waiting was too much while boarding. Moreover, food choices can be improved as well.

Flights on time, planes up to date with clean toilets, comfortable seats and working IFE. Helpful Lufthansa staff. Food was good, but can always be better, esp vegan and vegetarian food loaded from the USA. Overall great experience.

We were on a new plane with Lufthansa and everything was clean and seats were comfortable. Staff was courteous and food was good. The only airline that still provides real silverware and not plastic.
