Real quick RAF help please

search seems to be broken for me, i searched and couldn't find anything help so here's my q:

I bought two battlechests, on sale today for 13 bux at frys, im going to activate one and RAF the other one so they will be linked and i can boost with my main account, but will the triple xp happen as soon as i RAF the other account or will it only begin after the 30days of included WoW game time are up? Like do i need to buy a game time card to immediately benefit? i am not interested in the zhevra mount.

it happens immediately. they must be partied together and within 4 levels of each other. also link your first account too so you can at least get RAF grantable levels.

Main -> RAF1 -> RAF2.

boost with the main. the two RAF's will get the bonus since they're RAF, and should be within 4 levels of each other.
without buying extra time, you should get 1 month of this. however, to take advantage of the whole 90 days of RAF, i would spend the money and get them both 2months time card at the end of the month.
