It looks like Continental has joined Delta in promoting their partnership with US Helicopter service to/from Manhattan.  If you are flying on a C, A, R or Y fare you can get the helicopter for free, and if you’re on an H fare you can get it for only $45.  This seems to be working on domestic flights whereas it used to only be for International Business Class tickets. 

The deal on Continental expires on October 31, so if you’re going to take advantage of this deal, you’ll need to do it soon.
