Thanks, nsx. Four of us are traveling together. Two bought early bird; other two did not. (Sitting 2 and 2 is fine; we don't need all 4 seats together).
The two that did not buy EB checked in at T-24. Maybe not EXACTLY at T-24, but within 45 seconds of T-24. They got C12 and 13. Not that it matters -- the situation is what it is -- but would you expect that sort of boarding position, checking in very close to T-24?
I suppose it depends in part on how many A List, or EBCI buyers, etc..
