Baltimore to Boston. As soon as my flight was cancelled during the recent blizzard the agent confirmed me on a flight leaving in 5 minutes to Providence RI while the gate agents for the Providence flight held the flight for me. The flight to Providence RI still arrived pretty much on time despite the blizzard. Southwest delivered my bags to my door the next day. Everyone was courteous from check-in to arrival. I thought this was excellent service and much better than service I have gotten on the major airlines when things go wrong. Also no fees for bags no fees for drinks and pretzels onboard and I hear there are no change fees on this airline either.
