More than once my plane has been late on southwest and every time my connecting flight waited for me to arrive before departing. What a nice way to end a trip.
I'm far more impressed when my bags catch up with me in some remote location in the middle of the third world you have to give directions by people and landmark :) But so far they've gotten them to me without fail.
Unfortunately for me, alot of these flights are booked through companies I work for, leaving me few options, but I will expressing my preferences going forward, and not buying United personalyl ever again.
