I would think loss of the 4 CO gates would impact UA's subsequent strategies out of LAX. It's been so long I've forgotten if the loss was voluntary or mandated...

Edit: Looking back at an old thread it looks like UA gave 'em up voluntarily (who gives up gates at LAX voluntarily?!?!?!?) and AA picked 'em up because of a standing deal w/ LAWA to obtain returned gates. That kind of restricted LAX plans going forward.
