Just wondering if anyone has had any problems with gate checking a stroller with Air Canada. It says on their website that they really preference umbrella type strollers and give the collapsed dimensions. We have a Baby Jogger City Mini which folds flat, but I will have to measure to see if it conforms. I was under the impression that all strollers were gate checkable...is this just Air Canada? Our daughter will be 4 so if we have to check it with baggage we can as she can walk fine through the airport, but since we are leaving through Pearson it would be nice to have in case she wants to rest (or we need to move faster, lol!) Any insight into this would be great as we have never travelled with a stroller before. Thanks!
