The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

They made us board and then deboard due to mechanical issue which delayed the departure by almost 2 hours and we barely made our connecting flight. These quality checks should've been done before boarding not after.

Having to up charge for a seat assignment is not good. Delta can do better

I liked the friendliness of the staff. The cleanliness of all 3 planes.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

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

Nice to have free food and reasonable beverages. My seat screen was out. Crew tried to reset it but no good. Would fly WestJet again

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

They were on time and everything went as expected. The only thing that could be better was they didn't wait for us to get through customs to pick up our luggage off the carousel. An employee picked it up and was shoving it together with others onto a cart. Later we found one of our luggage was slightly bent.

Delayed boarding. Delayed taking off. Delayed landing. Missed our connecting flight. Our seats on this plane were not assigned until last minute, splitting up our family with kids. I sat in the last row next to the bathroom with so many people rubbing up against me to get to the bathroom the entire flight.

Another delayed flight. Then got bumped to a later connecting flight, over two hours later! Plane was hot and uncomfortable.

My flight was delayed three times then eventually cancelled the next flight was the following day scheduled for 1030 it was delayed I had to cancel reservations I had to put people up in hotels on the other end as they came out of town to pick me up all at my expense because WestJet couldn’t get it together I’m very disappointed in WestJet’s performance and how they handled the situation Get your customers to where they need to be in a timely fashion, even if that means putting them on your competitors jets Customer service should be number one I will think twice now with booking with WestJet

Arrival at Comox from, London,ON 6 hours later... No bueano

Poorly staffed check-in in Victoria. Unhappy WestJet person on counter. Then our flight was delayed by 2 hours, which meant our luggage failed to make the flight to LHR. Overall poor communications to passengers. Fortunately the flight from YYC to LHR was good and on time.

Generally good. However. The flight left 30 mins behind schedule with no reason given.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

We had a very long delay. First the inbound flight took a while, then maintenance, they “fixed it” to then do boarding and leave the gate, and waste a lot of time to have to go back to the gate and eventually deplane. Had to wait for a new aircraft, wait for a gate, and do the whole thing again. Instead of leaving at 9:50am we left until past 1. I could’ve not woken up at 5am, or spend some more time with my family if they gave more grace period of time between flights to give some time in case of any issues. But they have to make all and every dollar possible

No TV's. Seats are super uncomfortable. Crew was great!

This flight was canceled at the last moment and I was stranded in the Vancouver International. I spent the night there without compensation and the staff looked annoyed and wanted to get rid of the passengers without offering much help.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

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

it was great only downfall was that the tvs weren't working but the rest was great specially the wifi

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.
