Friends of ours flew to Disney at March Break a few years ago with a connection in Pittsburg. When they got to Pittsburg there was a massive snow storm & no flights were going out & SW couldn't guarentee when they would get them home (this was a Sat). They had to get home because the wife has cancer & the husband is a school teacher & they had to be back for her treatment, plus they didn't want to sleep in the airport with 4 children. They decided to rent a van & drive to Ontario, without their luggage, they ended up getting their luggage sent UPS or something like that on the Tuesday.
