Interesting side note (for me anyway, or for any aviation or geography nerds or budding "Action" Jack Barkers out there): If they adhere to the shortest Great Circle distance, they'll be going north almost directly over the pole. (Because the two cities are almost 180º of longitude apart.) The flight will likely track north across SE Asia, China, Mongolia, Siberia, the Arctic Ocean, then south through Greenland, Canada, Upstate New York and finally New Jersey.
