As if AA is chomping at the bit for that? Nah. Not worried about it. Worst case DL loses all of the gates in question (highly unlikely that would happen) and could make up most of the capacity through upsizing and whoever wormed their way in would have to then slug it out in a two front war with DL and SWA who have found a highly symbiotic synergy.

If the alternative was to sit back and subsidize a megalomaniac rogue super jumbo RJ operator, they will find a way to pull the plug on them.
