I don't believe that is easily publicly available information. But for the sake of rough numbers given 60 days in Jan/Feb looking at Westjet/Air Canada roughly offering 3 daily 737 and 9 daily Q400 flights from YEG->YYC assuming a 95% load factor and 95% of those passengers making connections that would mean about 66,280 passengers would be attributed to Edmonton and Calgary would be able to count 132,560 over that period towards their pax count. If looking at the round trip that doubles to 132,560 for Edmonton and 265,120 for Calgary.
Not a perfect science as there are still (albeit probably almost negligible) numbers of folks connecting in YEG from YYC. You can see how that contributes although I believe we are down in capacity from previous peaks we had through YYC. The other factor is some folks choose to still make the drive to YYC but I have no idea what those numbers might look like.
