Is that 2 hours mean legal to start, legal to finish? If I get stuck in a conga line that is 30 minutes longer than planned at JFK, are we legal to continue? And I wonder what the MEC sched chair approval means... that they can unilaterally at the MEC level approve 2+15 hour legs on the monthly schedules?

short answer, no.
long answer, hell no

Like many I am awaiting the language, and more info, but so far, unless that 117 blurb about having to have 6 hours behind the door is sacrosanct, I am not interested in this.... at all.
