I would go
Hey,
I don't mind 30 hours on a plane if the airline has PTV units, free alcohol and good meals. Plus I would accumulate miles and use them for a fun trip later on this year(:. And I would ask for a week off upon my return due to jetlag(hint you sleep on the plane and you have no jetlag or a little bit of jetlag and you have a week off to do something fun). Play the game you do what they want they should let you have time off for the 60 hour flight.
Good luck.
