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.

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.

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

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

Had a hard time finding my assigned seat. No attendants to assist.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

Plane still had screens for watching movies. Good selection too.

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

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

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

Limited water service in a 6 hour flight offered at the very beginning and end of the flight.

They delayed flight because lack of staff then missed connection. Never flying with kayak or weather

WestJet claims that tickets purchased through a 3rd party (such as you kayak) they cannot make sure they mention the luggage situation. We purchased tickets that wouldn’t allowed any carry on. WHAT!? So ridiculous. We bought them and there was not one single place mentioning that. Then on our departure the WstJet attendant was a super nasty rude person. Very unprofessional, unpleasant. She should be reprimanded and given some sort of training but I believe that won’t change her nasty disposition. On our return was great, the front desk gentleman was really professional, friendly and helpful. He offered us to pay $18 usd each for our carry on backpacks as they were small (instead of $90 each at the departure, she could have mentioned but decided not to do so. Didn’t print my boarding pass with my full name as in the passport and made the flight delay because the crew needed to correct it).

Scrooge airlines spoiled my last chance at Christmas with my 95 and 92 year old folks. and rest of the family in Calgary. Ticket personnel would not let me on without a passport and I always visit Canada with my enhanced driver;s License when I travel from the US

Flight was delayed due to mechanical issues to the point that I missed my connection and had to wait for 6 hrs in Calgary... thankfully I wasn't in a rush or that would have been annoying

It was an awesome experience flying with Westjet. This was my first domestic flight experience in Canada.

The additional charge for the WiFi was not worth it. Streaming a football game was a joke as it continued to lag will be requesting a refund

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

The Entertainment system was nearly useless because videos kept stopping then jumping over segments at random but closely spaced intervals. About 75% of the plane gave up trying to watch and then the gaps and jumps became shorter, It was terrible and made it hard to know what was happening since it was not a normal buffering pause where you still get the cont6en t. Instead the video would pause then jump ahead missing short segments and dialog entirely! The economy class seats on all flights have less and less legroom. I’m tall and the upgraded seats are no better for the leg room, not worth it. I flew from Toronto to Calgary….The staff at YYZ was awesome and kind. My flight’s (prior) incoming plane from Liberia had been delayed over 3 hours and the attendant quickly and kindly transferred me to the earlier flight that got me in hours earlier. Such a great staff!! Every staff member on the plane was very-very Canadian/Kind . Great job and attitude you folks! The plane itself was new and in great condition, except the issue with the video streaming.

I did not like ANYTHING about Discover....see my previous comments regarding our trip. I will do everything possible never to fly with Discover again!!!

Terrible experience. Flight was delayed then canceled. They had no clue how to rebook us. Had to wait in line to take to a gate agent for 2 hours. Absolutely terrible from start to finish.

Most expensive flight… and they are trying to pinch more and more money out of you. Baggage, snacks, pillows, headphones… — so many airlines do far better than this… surely a national airline can do better?

We have already filed a formal complaint with Air Canada and are considering filing a complaint with the US Dept. of Transportation. Air Canada was impossible to reach in the two days leading up to our flight despite multiple calls and waits of more than one hour. Their website is designed to prevent reaching anyone and simply puts you into one doom loop after another. In the end, due to Air Canada's lack of communciation and unresponsiveness, we could not take this flight. Depending on how Air Canada responds to our complaint, we may never fly this airline again and advise the rest of the world to do the same.

The crew and food were very good. The plane was dirty..

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Had to buy headphones. Which is sad. I did not so I listened to podcasts and slept. Free beer is excellent a d those pretzels are great too. Overall I feel Air Canada slightly exceeds Westjet for overall experience. But still more can be done. Like allowing guests to view a movie for free.

Flight was cancelled due to problems with the aircraft . Not much else to add . Itinerary was changed from yeg to Yule direct . Fine .
