It's odd but I flew more in the 1st half of 2008 than I ever had before (mostly travel for work). Made GM with Delta in May, and I might be on track to make PM...a MR tomorrow to the Left Coast will help
A lot of this year's travel was due to additional responsibilities at my workplace, but I did drive more for regional trips. Usually if a client is within 5 hours driving, I will drive instead of fly (though driving is getting more pricey as well). And I'm finding that more client training is taking place via video conference/WebEx than before in our shop.
