We normally choose Westjet over AirCanada based on pre-pandemic experiences. For our flights last year, Aug, Oct and Dec (to Fort Lauderdale and the last to Tampa), relatively last minute for all of those flights Westjet changed our flights so we were flying the day of the cruise, which I don’t do (too much risk with the Edmonton connection), so for all 3 we ended up flying with Air Canada. Everything was generally fine and I’m now less worried about booking Air Canada in the future. We had delays, but we also just had that with Westjet (AirCanada flight delayed 3 hours waiting for people to load our bags and then our flight crew timed out. Westjet delayed over 2 hours because of flight crew issues).
I like the experience connecting through the Air Canada terminal in Toronto much better. For the way down to Florida, there is a separate security area and customs area for connecting passengers so we were not in the huge lines that the people starting in Toronto airport were experiencing. Also, on the way home, US to Canada, the connecting passages go to a separate customs area and never leave the secured area, so you don’t do security again. The lines in the connecting area in that terminal weren’t that bad. Even without Nexus, the connection time was not too bad.
We just came back from the Celebrity Equinox in Fort Lauderdale on Westjet. On the way down, in the Westjet terminal on Saturday morning at 6 am, you leave the secured area and are out with all of the passengers. There is no separate connecting area. We had Nexus, so we were fine and everything went quickly, but the regular security and customs lines were huge. Without Nexus I would have been concerned with only a 2 hour connection. On the way home on Friday night around 5:25 pm, there was a customs hold and only connecting passengers were able to leave the plane. I’m not sure how long the others were held on our plane. There is no separate area for connecting passengers in this terminal, you go to the main customs area, through baggage (we did not have to pick up bags Westjet US to Canada but some flights do), then out, upstairs and through regular security. The first line to get into customs was one line, they didn’t care if you were Nexus or not. We waited in that line for about 40 minutes. You then go to the customs hall where the regular passport line was huge (I’m not sure how long that took, but it didn’t look good). There was no one at the Nexus machines so we were done and out of there in minutes. The regular security line was also huge but again Nexus was fast. Again, on Friday night without Nexus, US to Canada, I’m not sure that a 2 hour connection would have been enough time. With Nexus the entire process took us right around 1 hour.
