If you did not get a seat assignment you can always log into your reservation and choose a seat then. No need to wait until 24 hours before the flight. You should have been allowed to choose a non-premium seat upon booking also.
Thanks for the info. Nothing but premium seats were available at booking, so I guess it's a pretty full flight.
