Another gate reshuffle:
Spirit has moved to terminal 2 and has taken over the G gates AA got from Alaska. AA has gained the gates in L that Spirit was using, and now mainline flights depart from L2A (Previously AA a year or so ago), L5, L7, L9, L10B, and L11. With the exception of the new gates L26 and L27 (shared with Key Lime / Denver Air), AA now operates out of every gate in L. The additional gates come from the common use gates in H and K that are used for EI (Departures/Arrivals), IB, and BA (JL has departed T3 for quite a while).
In the latest gate reshuffle, AA is set to lose 4 gates (from somewhere), however it's likely to be a battle as the usage statistics don't appear to have been calculated correctly.
