The crew all the way from Medicine Hat to Thunder Bay were wonderful! I think Selva was the name of the stewardess on my flight from Medicine Hat to Calgary and she was delightful! It was pretty early in the morning and she was the right amount of pep without being overbearing. She was very organized and professional as well thank you! My flight from Calgary to Toronto was fantastic! I've been on large planes before and the boarding process was very well done by the crew. I was bumped to a window seat (such a blessing) and the selection of entertainment was great. The plane was very clean and modern. Vic the stewardess really stood out and was very kind and professional thank you Vic! I don't remember the names of the ladies on my flight from Toronto to Thunder Bay but they were fantastic as well! Its always a rough time flying into Thunder Bay that late but they made the journey as comfortable as possible, thank you both! All in all thanks Westjet team you did a great job and I look forward to flying with you again!

The food selection has been better in the past but due to Covid it is understandable. This particular flight did not have any entertainment and the Air Canada App did not work to access movies.
