I don't have any experience with bike bags, but I really regret buying an ice hockey bag with wheels, as does our goalie. They add a lot of extra weight to the bag (not just the wheels but the frame to keep the bottom of the bag stiff; maybe bike bags already have this?) and in many cases, you can't really use them anyway, so you end up carrying even more weight than you would have with a regular bag. It might not be such a problem at airports, though, where there are flat surfaces and escalators.

One major failing with hockey bags on rollers (that I've seen) is that they don't have an extendable handle for pulling the bag, so you end up walking along with the stupid thing behind you, nipping at your heels and hitting you in the knees the whole time. No fun.
