LGA $3.6B terminal expansion... for the other airlines.
Evidently, according to this picture, we'll run into the buildings when using the taxiways.
La Guardia Terminal Update Sought - WSJ.com
But I have a better idea. Call it the Scambo idea.
First, we bulldoze all but the main terminal building, no more arms/legs/extensions and jetways. Now let the airlines fight for the few gates that are left.
Then bulldoze everything on the south side of Grand Central Parkway to Astoria Blvd. We can use that to build a grand terminal and parking area. Sadly for RJs, but just maybe one day mainline jets!!!!!!
Then build a walkway from our terminal in LGA to our terminal in JFK.
