I'm AA Platinum and Delta Gold Medallion.

Qualify by: Miles; segments would barely get me to the first tier or even just miss it

Live in: Boston, Mass., USA (East Coast)

Average mileage per segment: About 2,000 on AA (trans-Atlantic and trans-continental flights); 1,500 on Delta (have to change to the West Coast)

AA: If you're listening, I'd drop Delta and focus on you if Exec. PLT wasn't so far out of reach for anyone who uses discount coach tickets - or if you offered some other real incentive partway there.
