From a real estate point of view LAX may finally be abandoning the idea of widening the space of the northern runways. The image posted earlier was based on the assumption that the aiport would widen the space between runways, similar to the southern portion of the airport, This would necessitate eliminating the extensions of T1-3. Delta would need access to TBIT gates to match their operation to say nothing of expansion. Interestingly a connector for TBIT to T3 was planned but dropped as a combination of T3 limitations and because VA no longer boards from T3.
There are so many issues with LAX renovation/expansion I wonder what may is possible. The imminent issue may be legal. If this increases total LAX gate count then there will be lawsuits from NIMBYs. If the city owned gate space is reduced than LCC airlines may also sue.
DL is also not the only carrier making long term moves. LAX has floated taking over Park 'N Fly and either creating another extension for T1 or a Terminal zero. Expect Southwest to be vocal on any move that will limit their vision.
Lots of parties and lots of lawyers will be scrutinizing this.
