I think the SWA taxi speed thing is overblown. I'm in a relatively senior base and I don't see the guys taxi any faster than at any other company I've worked for. There are exceptions but they certainly aren't in the majority
I'm not sure. I got bitched at by one of your coworkers in Midway yesterday and we all still had to wait for 15 minutes for inbound traffic on the 4's.
I figure why taxi fast when I have to jam on the brakes at the end of the taxiway only to sit and wait.
