It's unfortunate that UA dropped PAE service... and Alaska doesn't serve BHM.

If you were flying in Economy, I'd probably advise you to keep your current flight, with the knowledge that you could be moved onto the later flight if necessary. In F, though... you're very unlikely to find two F seats available on the day of departure from DEN to SEA.

Wheelchair service sounds like it might be the way to go.
