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

We were late boarding, but it all worked out. So, no problem.

It was good but not comfortable seat with the long legged persons.

No problems here. WestJet does a good job, even on their short haul flights

Boarding was fine, but then we were delayed a while due to some baggage issues, then de-icing.

Tried to reserves seats and WestJet My Trip shows not available until 24 hours before the flight. When check-in was finally available and I tried to get seats again I was not able to get to select seats for me and my wife together. All in all, was not able to select seats together on Kiwi, paid extra for seats on Westjet and still did not got seats together, not pleasant for such a long flight and with my wife not very good with flying, disappointed on the way the system works with regarding to seats reservations, even with paying extra for them.

Flight full. 'Volunteers' to check hand luggage. Checked hand luggage is lost

Not the fault of WestJet but we had to wait in the plane on the tarmac in Cancun for 1 hour.

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.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

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.

There was no food or entertainment on this flight. Great flight crew though
