I know if I looked at the fare basis before purchase, I would know what I purchased but I didn't. I have a one-way ticket with two connecting flights.

Flight #1 : Short CRJ hop Fare: V
Flight #2 : Long transcon booked in biz Fare: I

I'm likely running into IRROPS for these flights later today. What will the agent rebook me in? Coach or biz? How do agents address split fare tickets like this one? Will they count the fare class on the longer leg?
