For your travels, there are ways (if they seem reasonable to you) to maximise your earnings. If traveling to Europe, you could route your flights as follows: X-LAX-JFK-X and earn 720 TP for a return flight, that's halfway there already!
Even then, you shouldn't have any trouble getting there. It may be interesting to optimise if you want to grab an upgrade voucher, though (those could be used to upgrade from J to F on a transatlantic segment, if availability permits).
