It is all a matter of how much money you are willing to shell out for a few hours of luxury.
The mint seat is very nice (suite is even nicer even though the seat is not really different from the other mint seats), the service is usually excellent and food fairly tasty.
I think it is a much better/nicer experience than United BF on the transcon service.
If the difference is not going to affect your bottom line (at the end of the month/year) then it is a luxury worth taking. I don't think you will be disappointed.
