Let's not forget the infamous USAir baggage handler sick-out of Christmas week in 2004 which turned PHL into a luggage graveyard. Two aquaintances of ours hit MCO sans luggage and did an unscheduled 'fashion stop' at Wal-Mart, all that was open at that time, in orded to have clothes and toiletries for their vacation. I understand they didn't get all their stuff back until after they returned to PA. We were scheduled to connect through PHL that New Year's Day via USAir, so I had all the other carriers at PHL on speed dial on my cell and we each had a carry-on with 3 days of stuff. All went well, but you learn to prepare. If Delta gets past this crisis and there's nothing scheduled to hit the fan during or before our March 2007 trip, I'll probably use them, but with reservations, pun intended.
