I'm a segment person also... home in Bloomfield Hills and office in Marshall... FNT-DTW and on to somewhere works for me.. as do LAN, AZO and every once in a great while, GRR. The segments do build that way for sure.. and when much of your flying is headed East from Michigan, that's about the only way to get/keep PE status. My best segment run this year was FNT to Austin, through Houston... 6 total for that one. Very often, but not always, the fare is less.

Headed to Chicago this AM and for that its best to leave right from DTW... and now, off to the gate.
