Wow, what emotions over wild speculation. I can probably add some perspective on a few things though.
On this flight, the "crew van" has only 2 in it (I've done this trip a bunch). One CA, one FO. The FAs fly the flight from ATL and back as continuous duty. Unless there's lively conversation, I can see how the FO probably didn't notice.
I've only flown with one FFDO, but the procedure I saw is to go to the first TSA agent and tell them in a low voice them your FFDO status. Since this shouldn't be announced to the world, you have to get close so they can hear you. Where they go from there, I don't know, but that first contact is probably where it was noticed.
Doesn't everyone realize that everyone in the airport is looking for the next "drunk pilot"? During football seson, I like to go to the Budweiser Brewhouse in ATL to watch a game and have a meal if I have a while to wait. About every other visit, some passenger makes the "I hope that's water" comment. They're joking to make small talk, but it doesn't take a rocket scientist to know that we're being watched.
So why even drink on the road? Do we need it that badly? Technically you could drink at lunch and be legal to fly on this flight. But why risk it? To blow a .04 at midnight west coast time, that would mean A LOT of drinking at lunchtime. If this is all true, Randy has a serious problem and I hope he gets help.
Let's be careful out there....
