First time

Evening all, I am new to this site and thought i would let everyone know that I am about to go on a trip with work to America, this would be the norm for a lot of people on here, however I have never travelled on my own, neither have i ever been to America and this is the first time i would have ever stepped on a Jumbo. I am excited but nervous as im leaving my wife and young daughter for the first time.
Any travel advise / best seat would be appreciated. My flight number is VS027.
Cheers
Dan
