What fixed compass heading would hold to fly from JFK to SFO (assuming no

Is it a trick math question? It's certain won't be the great circle
route, which has a continuous changing magnetic heading to hold.

Given the difference of magnetic variation between west coast and the
east coast, I'm not certain this can be calculated using a math
formula. Such a magnetic heading can be deduced by a computer
simulation using the brute force method.
