ok.... Im in F, up'd from S class. Id like to leave on the 9am flight connecting with my original in IAH (eliminating my 3 hour layover).

If I pay the fee and CO is able to confirm me into S on the new flight, will they also confirm me in F, if F is available, being that I was in F on my prior flight? or, will i just have to wait for the 3 hour or airport EUA to run?

thanks
