The Canadian carry-on ban means a lot of people will be checking bags they never intended to check. Since you never know when this policy will show up in other places or when you’ll be gate-checked, it might be wise to choose the most rugged carry-on possible for 2010. The lighter/cheaper fabrics may be in danger of damage in the checked baggage blender. Unfortunately, more rugged usually means more expensive. Securing zippers and outer compartments is something to think about, too.
