While most pax have coffee in the AM to get them going, the disheveled guy (with AA EXP tags) sitting across the aisle from me on this morning's MCI-MEM DL flight was having none of that. The first Jack at about 6:10a while we were at the gate, then two more during our 57 minute flight. Got a sense this was his all day beverage of choice. Wow, no wonder this guy weighed 350+ and spilled out of his F seat.
