Wheelchair assistance at SEATAC -- allow extra time?
We'll be flying on a Monday afternoon on Southwest from Seatac, in October. There's four of us, two middle-aged and two elderly. We won't have our own wheelchairs, although we'll need wheelchair assistance for the elderly passengers, at least, and probably for all four of us so we can stay together with them. I've already made that request to Southwest Air.
My question is: about how much extra time should we allow at the airport to wait for wheelchairs or a cart and driver to become available? Thanks!
