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

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

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,

Flight was good, crew was excellent. No complaints at all

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

I didn't think about not having the right app for wifi because my connecting flight was with Westjet and when I took off from Seattle I was thinking I would use my wifi, but realized I couldn't on my Westjet app and I did not have Delta's app downloaded.

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

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

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

The trip from LAX to Calgary was aboard a 737-700, which is more than twenty years old. Service was fine, and the food was good, but there was no inflight entertainment, and no WiFi. The flight from Calgary to Vancouver was also delayed more than an hour, due to congestion on the Calgary tarmac. And no food service, but there was in-flight WiFi which made a big difference.

Flight got delayed But satisfied with the pricing of tickets

1didnt have wheel chair I ordered wheel chair in my ticket flight

Flight was oversold. Seats assigned to multiple passengers. Delay 1 hour to sort out.

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

It was pretty straight forward, no glitches or hidden costs

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

Selected seats 5 months prior to date. Had email confirmation and seats were not honoured. Family did not sit together
