The absurdity of this is awesome.
But imagine paying another $500 for 8 segments at one time, then doing segment runs instead SAN-PHX or SEA-PDX? One could earn 8 segments per day, or 240 per month. That could earn you Alaska MVP Gold, American ExecutivePlatinum, and Delta Silver (likely with CC waiver) from scratch in one month, plus a boatload of miles if you earn 500 mile minimums.
