The gate personnel and flight attendants were all friendly and diligent. The poor attendants from London to Calgary were 2 colleagues short, as one of their team broke her leg on the way to work, and the other stayed with the invited colleague. I felt bad for the crew, but they did a great job regardless.

Flight delayed missed connecting flight crew not very helpful very frustrating customer service
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
The plug in to charge our phones are all loose my block would not stay in!!
My flight was cancelled due to weather but Westjet got me on a new flight in a timely and efficient manor.
Again, flight was late. It’s expected of this airline now i guess.
I rated westjet poor on food for not accepting debit to make in flight purchases. This is dumb.
Delayed 8 hours, This is the 2nd time in a month that my flight was not on time.
The snacks could have been better, and maybe some warm drinks instead of just water cause it was very very cold.
I like and appreciate the attention and patience from all west jet personal to my senior mother. Thank you!!!!
