When I have traveled on Air Canada to Terrace I have used a large duffel bag which is about 40" or 42" long and about 16" dia or so. You can google on popular auction site that is where I got mine. I then put my rods in this duffel (4 pc 12.5' Spey rods) along with my waders, boots, rain jacket, shaving kit, I will also put in fishing clothes in the bag ( these are place in a plastic shopping bag inside the duffel). I make sure the weight of the bag is below the weight threshold. I then take a carry on bag with reels, camera and additional clothes. That way only one bag is checked in and it costs me the standard bag fee for one checked bag. I do the same on other airlines when I go fishing elsewhere. I use to use a ski bag when I had 2 pcs rods but it does not work well in terms of getting wading boots in also would be charged more for oversize bag.
