When is Philippine Airlines going to have Flights here in NYC?

There are a lot of factors -

1) Competition - remember, that PAL may not have any non-stop/direct competition on the route, but airlines such as Korean Airlines, ANA, JAL, Singapore Airways, Cathay Pacific, Air China, China Airlines, Thai Airways have all marketed themselves as premier airlines with convenient connections to other parts of Asia. Seeing that most of these airlines can command such a large passenger base they split the passengers wishing to go to the Philippines into smaller fractions, very difficult to pick up a small market against such strict competition.

2). Aircraft - at the time, PAL simply does not have the aircraft to do the route economically (the 747s might be to large for such a new route, and the A340s are gas guzzlers that may not provide as much fuel economy or too much capacity), and or have the planes to do the route at all (it would require 2 additional 747s or A340s to be designated specifically to the route) as well as crews and all of the other fixings.

3). The money - remember - everything costs something. In order for them to start they would need a large expenditure - money to acquire infrastructure at an east-coast airport (some of the highest premiums in the world), maybe eastern-coast based crews, and not to mention the fact that recently they have been starving for money - they have no real reason to waste money on a new route right now.
