AA used to have two transcon desks prior to the merger. They were extremely busy and went fairly junior. There were lots of medicals, passenger misconducts, and mechanicals. Structured routes were common for all of them during the summer months. CDRs out of the northeast often ran up against tankage and max takeoff weight on narrowbodies. Turbulence common crossing the mountains.
Workload in terms of flights was similar in number to other domestic desks but these flights were airborne for much longer so 20 airborne flights were not uncommon.
After the merger, it was decided to split up the transcon flying among all the general population desks.
