Pros: "seat space was great and I was lucky enough to have medium size passenger next to me :-)"
Cons: "Can't really think of anything . . . my expectations were exceeded"

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

The comfort is typical of what I would expect from main cabin. I've been on flights with other airlines where the seats needed to be changed, the cushions were non-existent. So happy this was not the case. I enjoyed the movie selection. Happy pillow and blanket was provided since I forgot my own. The food was also ok. Great that we arrived early and my luggage arrived undamaged. Again in the past (not with Delta), luggage was lost or broken.

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

The 676 plane is much more comfortable in business class than the A330 and he food was a little better. I didn’t use the entertainment.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

It was okay overall, but it was a 4 hours flight and the only thing we got was snacks, I really expected breakfast.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

My wife and I had an uncomfortable experience with your WestJet ticket counter rep at the WestJet Priority Member ticket counter at YYC (Calgary) on May 15, 2024. I not knowing this individual’s exact name, however, in order to easily identify her, she was one (of only two at the time) ticket counter reps at your Priority members ticket counter check-in, upon our arrival around 12:15 p.m. She was a Caucasian woman with blonde hair, and wore spectacles, approximate age being probably somewhere in her 30’s or 40’s. Background: After arriving in to the West Jet terminal in Calgary (YYC), I asked a terminal employee where the West Jet check-in ticket counter was. He told me, “Column 16”. My wife and I continuing to walk through the terminal, we finally arrived at the Column 16 area, i.e. this woman’s ticket counter area, which we discovered later was the Priority Member ticket counter. However, I was simply going by the directions given to me by the previous employee, i.e. “Walk to column 16.” Standing in her line (my wife and I being the only people in her line at the time), I tried to get her attention, and I then gestured to her, motioning to her as if to ask her if I should then possibly leave the waiting line in order to then proceed to walk up to her ticket counter. She never really motioned me to come forward. I sort of had to figure this out on my own, as my wife and I then finally decided to walk forward to her station. From this point on, after I arrived at her ticket counter, never once did she ever look me in the eye. She was always looking at her computer screen, or down at the ground, as she and I occasionally exchanged conversation with one another in order for me to be able to acquire my boarding passes from her. Shortly after she began servicing us, she commented that her work section is for Priority members only. Fair enough. I did not realize this at the time. Wishing to be polite, I then mentioned to her that, if I should, I could then walk over to the regular West Jet check-in ticket counter in order to complete the check-in process. She remained quiet, never responding to this goodwill gesture of mine. She continued to work in order to print out my boarding passes, and then finally handed them to me, never at all the entire time looking at me. I told her, “Thank you.” Never once did she respond. My wife and I then walked away. Even my wife commented to me afterward that this woman absolutely never looked at us. I cannot say that this attendant was outright rude. However, she certainly was not at all warm, congenial, nor friendly. Additionally, … After getting on the plane, we then discovered that she had needlessly assigned us seats in the very last row of the plane, these being the seats adjacent to the restroom back wall, thus, unfortunately not at all reclinable. I think that the row number of this last row of seats was 30. [However, I am not sure.] How strangely awkward that we were assigned these uncomfortable row of seats when in fact the row immediately ahead of us, i.e. I think that was row 29, had two vacancies, which could have otherwise easily seated my wife and me. That is, my wife and I could have easily been assigned these more comfortable seats, which would be reclinable, and then row 30 could have otherwise had instead our two vacancies. After our flight departed, and the fasten seatbelt sign was turned off, my wife and I had hoped to “jump seats”, that is, to leave row 30 and instead sit in row 29 to utilize the reclinable seats. However, another couple apparently had the same idea as us. That is, these other two people, for whatever reason, decided to leave their previously assigned seats, and instead, seat themselves in row 29. Thus, my wife and I were stuck with these miserably cramped row 30 seats for the entire 3.5 hour flight. To reiterate, the WestJet rep we originally encountered, knowledgeable of the plane lay-out as it appeared on her computer screen, could have easily assigned us the more comfortable row 29 seats, instead of the non-reclinable row 30 seats.

Keep better track of bags. Not sure how they got lost. Also not sure why it took two weeks for us to get them back. Had to buy a bunch of necessities because they were packed.

Our trip was booked to be 2 hours after arriving in Calgary but it was changed until the next morning forcing us to stay overnight in Calgary with no compensation

Was the longest flight I have ever taken to Orlando. Not Westjet’s fault necessarily. There was a traffic issue in Orlando. We sat in the airplane for about 2 hrs before leaving Calgary on a 5 hour flight was just a little long to be stuck in the plane. Once we arrived in Orlando we were stuck in traffic on the ground for another 30min. I guess maybe the flight could be delayed so boarding would have been later so we wouldn’t have to have the discomfort of being on the plane so long.

I like WJ but I don’t like traveling anymore

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

4 hour delay, lost our bags, staff was loud and it was an overnight flight

The Wi-Fi was unavailable on this flight for some reason.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

T hey did a great job. Flight was on time .

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

It was an excellent experience, traveling from Toronto to Denver with United.

I think Air Canada is the only airline I've flown where they don't give you at least a free cookie.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.

Economy seats were surprisingly comfortable, and snacks not too bad. Checked luggage arrived at destination without problems. It was annoying to wait until last to board as lowest-tier seats but understand it’s difficult to gauge when loading a full plane At least checked carryon luggage seemed to come off first. Annoying to have to use app to order food/drink when wifi availability didn’t allow time for it. Advance communication would have helped Food on menu seemed highly processed and unpalatable, overpriced and over packaged. So maybe a good thing to have missed chance to order

All but one of four were on time. One was delayed for an hour

The boarding process in Toronto bad as they share space with domestic flights and when those domestic flights come in you are locked out behind closed doors until they are done and then its a mad rush to get your boarding gates and board. This is not so much due to Air Canada but with the GTAA, but Air Canada could use different gates especially early morning in order to prevent such travel angst.
