Great and comfortable aircraft. Good food and the staff was amazing

Very short leg - too short for any meals/snacks or entertainment.

We missed the flight. I had a passport issue and told the check in desk that I’m trying to resolve it but when I got approved for entry to USA at 3:32, one hour before departure, the employees had left the desk at 3:30. I tried calling and texting the numbers on the sign. No luck. Waited till the agents came back and couldn’t get a flight to our destination or close, so we flew to Las Vegas instead and drove 6 hrs to San Diego where I missed one night’s stay and the car rental that was reserved there. Extra car rental and hotel in Las Vegas was over $300. Lost tine and money. I wanted to extend the trip by two days but the $1600 SAVER fare wouldn’t let me make changes. Hours on the phone to find out there are no exceptions and no credit if cancelled in advance. Very disappointed. My son’s first vacation with me in 17 years. Wasted a lot of money. Next time I will use a local travel agent.

Booked a first class ticket and was not even offered a bottle of water…or a cracker…absolutely zero in flight service on a 1 hour flight

The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

Well to start the crew is Seattle told me my luggage would go right thru to Ottawa. Not so before landing we were told to pick up luggage at carousel 8. On landing I asked and was told to pick it up & take it to the conveyer to be sent to Porter. Staff said Alaska always says that but no it doesn’t happen. As for Porter they said the flight would be a bit rough, so they offered a free wine or beer. Only snacks were provided on each flight.

Boarding was late with no communication. Flight was over an hour late with virtually no communication or updates. The app showed we had departed and were scheduled to arrive on time even though we sat on the tarmac for nearly an hour. People who were using the app to track our progress to pick us up were given erroneous information. Flight attendant was snooty when asked why app was showing us as delayed and arriving on time even though we had not left and ultimate’s not leave for over an hour. Just poor and arrogant.

My luggage was lost and doesn’t appear to be arrived any time soon.

Check in was a nightmare. We had about 15 people ahead of us but were in line for 45 minutes for priority passengers. Two people were checking in dogs and it took them forever. They even took the dogs out of the kennels to weigh them separately. Crazy! Then when we reached the front of the check in line we were told they couldn’t check us in because we were too early. Had to wait 19 minutes to check in and then check ourselves in and get back in line to drop our bags. This was first class! If I can avoid it I will never fly Alaska again. I sure didn’t get what I paid for.

It would have Bern better if the flight was on time.

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

Leg room is a problem the plane was dirty and there were no movies available on the app

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

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

Westjet is the worst airline in the world, they are absolutely terrible, there are to many things that happened that I can't explain in this message, I would like to talk to someone about my ordeal. I am partial handicapped and that I can only walk a short distance, I calculated how far I walked and it was more than a kilometer, the pain is so bad today I have to go to my docor, they told me there was nobody available to take me to my gate, this is just one instance. This is not finished yet, I need to contact westjet and let them know about my trip from hell

They lost our luggage and didn’t return it until 15 days AFTER we got back.
