It gets worse than weird. After a while, stepping onto a plane seems as simple and stress-free as taking a shower. You just do it. Two Sundays in a row of SFO-ORD round trips, one with a 90 minutes layover (left home at 9pm, back at work in time for opening the next day at 11am) and IT WAS JUST TOO EASY! Oh, and that one I purchased the ticket less than 24 hours prior when I noticed a reasonable fare had just gone up.
And I'm actually getting work done while flying that I haven't been able to do at home or at work due to interruptions. Plus your smart phone brings the office to you, whatever airport you're in.
It's a bizarre lifestyle, to be sure.
