Well, as you know, SAS only gives 25% in many booking classes on US and UA. The simplest and cheapest is flying PS from JFK to LAX, Cheapest class 1 way (2500 x 25% is 625%, V class the other way 2500, total 3125.

Price is 384 USD and is available to do Saturday 27th. Add 90 dollars for V both ways.

Good luck!!
