Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

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

Overall service is good. Just thought foods need to upgrade for economy class

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 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.
