I've actually gone back to DL, temporarily anyway. Having achieved Cockroach Preferred again on USAir this summer, I'm making a last ditch attempt at requalifying PM on DL...even to the point of flying to GRU (Sao Paulo) on an L fare next month. 3 times I flew there this year on AA and I upgraded to business every time. Not bad for someone who never made EXP. I don't look forward to DL coach on this trip and it may persuade me never to fly DL again, but at least I'll possibly enjoy free CRC drinks for another year.
