I use wheels for my 2 nd bag. If Dean at Four Seasons Travel is getting your tickets and passes and for some reason they don't reach you at least a week before departure, call him at 800 331-3136. He never has failed to get tickets out on time, but there could be a first time. It all helps. Not too late to start right now.
