Help! I am flying tomorrow (4/26) on an E190 (US Airways) into Philadelphia, and then connecting to out west. I would like to know the size of allowable carry-ons; will my normal Tumi rollerbag make it? I have a "tight" connection, so I definitely won't go the route of checked luggage, and last experience with waiting on the jetway for the gate-checked luggage resulted in a missed connection (love having to wait for the bus to go from F to A ...!!!) So, the rule is if it doesn't go on the plane with me, then it doesn't go .... or, a FedEx package gets sent. Thanks!
