I've opted to drive when and where I can.
No rental car needed, no undue delays (my flight a couple weeks ago had a 3.5 hour delay and meant that I didn't arrive at my destination until 2am local time and 4am in my normal time). As it was cross country I didn't have much choice but for closer trips (~400 miles) I've been driving for years.
Well, 3k miles one way is a bit of a drive...bummer.
