With regards to JFK
I guess your asking about AA
's terminal project, here's some quick points.
The project was originaly slated to be completed in 2006, due to AA
's financial condition construction has been slowed. The new date for completion is 2008, however the C concourse (mid-field) will open by 2005.
Also the project is being scaled back, originally it was envisioned as a 55 gate terminal. The terminal will now have only 39 gates, the 15 or so less gates were to be for Eagle RJs. American has scaled back Eagle operations at JFK
drastically since the Terminal project was launched, they have dropped all their Eagle routes with the except for BOS
The project will replace AA
's current Terminals (8 & 9) with a single terminal
Anyway here are some renderings..
