I am curious to hear how flying J is justified by other companies?

My company does have a policy that allows for flights over 7hrs to be booked in J. The catch for me is that I am with a newly established division that is barely profitable (They hired me to eliminate the "barely" ) and I am my own P/L.

Almost all of my trips are international and I expect to fly over 300k this year.

If an economy ticket is $1500-$2000 and a J ticket is $6000-$8000 where do you find the $4000-$6000 value in the J ticket?

If from a personal financial standpoint, I have a hard time justifying the purchase, how can I expect my company to?
