We are flying YOW-YYC in late Nov on Porter and are looking forward to it (even though we have to go via YYZ). When we booked our Jan cruise out of Tampa, Porter had not yet announced their new routes to various Florida destinations so we were stuck with booking AC Rouge (ugh!). However, I see online that there are very, very few seats booked on our flights so if AC cancels or amalgamates our flights I will cancel, get a refund and switch to Porter if there are still available seats. Would be considerably cheaper too.
