Next Day Option?

I'm in Vegas right now and have the luxury of not having to be back in the days after my flight back to the UK.
I know that my flight back if full. So because I'm in no rush....
What can I expect if I give up my seat in PE and take the following days flight?
Thanks for any advice,
AC
