I was about to start a thread entitled, "What's with 6C and 6H on the new 767 C cabin?" I've recently made some schedule changes to IAD-EZE, IAD-CDG, IAD-LHR flights. When I checked the available seats (starting as if I were starting a new reservation) for as far out as I went, these two seats are blocked -- all 767 flights. Crew definitely has the F bed and the seats by the mid-cabin galley, so that's not it.

So, "What's with 6C and 6H always being blocked in the new 767 C cabin, even when there's not another seat taken (flight after flight after flight)?!"

Hunch: They're plums to give out later, just as F seats are held back until the last minute, for instance, between BOS and IAD on the 319 and 320. Though I don't know for whom... They're (6C, 6H) just as blocked from me as they are from everyone.

OK - I'll put it out there: It's a discreet GS perk to hold them back.
