Delta has occasionally pissed me off royally but when it comes down to it, I consider it a safe airline that usually gets me where I am going within a reasonable time. I don't mind ATL or DTW as hubs. Then again, maybe it's because I went to college in Atlanta and started flying whenever I could and Delta was the airline I got used to. I've been with it through highs and lows in its operations over the last 35 (gulp) years. But maybe it's really that it is like a pair of old slippers. I'm just used to it and while I still get a kick out of flying most airlines anywhere, it's the one I keep coming back to. Besides, I'm on the way to the 2MM mark so there's no reason to stop now.
