although I am supposed to be wrapping up work stuff, I will take a few minutes to speculate about this frustrating question one more time

speaking of "frustrating" ... I am currently #29 of 73 on the upgrade list for BWI-ATL at 1745 this evening (it's a 739 with 160 coach seats) ... luckily I was able to switch from a middle seat to the "bulkhead" window thanks to someone either SDCing or cancelling, and my ATL-SEA upgrade (also a 739) cleared a couple days ago
