Our bag was lost so that made unnecessary chaos On our trip

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

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

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

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.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

The staff were the friendliest I have encountered in years. Absolutely great!

Plane changed to one with no entertainment system or ability to serve hot meals

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Terrible. First my return flight was rescheduled to a terrible itinerary. Paid for window seats where there was no window. All of my seats were mediocre or terrible despite paying in advance for them. Zero onboard entertainment- it didn’t work or wasn’t available. If it was available there were zero instructions provided. I also didn’t like being forced to check my carry-on luggage. Delta screwed me around on the way home with a 2 hour flight delay that caused me to miss my connecting flight so my luggage did not come home with me but had to be shipped on a later flight. Just grateful they found it. But Delta attendants lied about the delay - a supervisor at an info booth assured me they would compensate because it was the fault of the pilot arriving over an hour late but when I went to the boarding gate to get help with this they insisted it was a ground problem in Toronto and not Delta’s fault BUT another flight to Toronto was going around the same time with no delays and West Jet agents in Toronto said there was no notice of any ground delays at the airport (which I have on video). When I went back to the info desk to find the Delta supervisor she was gone. I had to run through Toronto airport asking any availabile West Jet staff I could find to book a new flight home as I didn’t have a connecting flight anymore. Baggage wouldn’t help OR give me my bag back. Because we were one of the last flights into the airport all staff had left. I finally decided to go through security to find an agent at a boarding desk and was lucky to catch one before she left to get booked onto the next flight home in the morning but I still had to spend the night in the airport. It was awful!!! I was scared, travelling alone and desperate to find help - which was a extreme challenge. Maybe 2 out of the dozen people I asked were pleasant. The rest difficult. I felt betrayed. Oh and I kept getting directed to the information desk in Toronto airport but no one was on staff and I used the phone to try calling someone but I kept getting useless recording. I will not be flying Delta or West Jet again. It will be a long time before I feel safe to travel again. Many tears. This was an awful and highly stressful experience.

No access to any entertainment No food other than a cookie or pretzels even tho flight was over the supper hour Seats very close together and very little leg room Staff was very good

Good. Would be better if the carry on baggage was free.

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

Plane should have entertainment, instead of people paying to use wifi

Westjet has been absolutely terrible! Flights continually cancelled. Took 4 days to get home. Would have been 5, but we booked last flight with another airline after our Westjet flight was cancelled. Even pilot on original flight looked frustrated! Funny how they say cancelation is weather related, but they still have more than 1 other flight leaving to same destination on same day, but of course those are all full. This happened more than once on this trip. Two weather related cancelations and 1 mechanical. Not sure if the last flight even went ahead. Felt so sorry for families with kids and babies, and the older travellers. Felt like we lived out of suitcases and airports for days - SO RIDICULOUS! Next to no help from Westjet staff at airports, but it appears there is nothing they can help you with. Westjet has made it that they are unreachable when you need them! People were getting extremely frustrated, and rightfully so. Additional costs to us really added up, but Westjet literally DOESN'T CARE! Final straw was when we had to pay $1280 on a different airline (economy) trying to get home after another cancelled flight. Westjet will be refunding us a whole $140! Can't believe how this airline operates. We will never, ever use them again!

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.

No Charging ports for personal electronics, which were required to use wifi entertainment.

Rushed, the boarding was a great deal like a Chinese fire drill.

it was red eye flight, it was ok, there was beverage service, thats it i didnt care much as i wanted to sleep

Everything went smoothly. I appreciate the selection of free movies.

I like the friendliness of the crew members. I think the snack could’ve been better instead of a small package of pretzel. I like that they offer me something to drink.

The TSA agents in Phoenix were incredibly rude and confiscated belongings that we wanted to check. The flight got changed without our knowledge to a worse situation. The whole thing was terrible
