identify this movie - Cheesy-looking pac-man monster in an alternate reality where most people disappeared

I think this was a made for TV movie, and a Stephen King novel, but I just looked up his works and nothing rang a bell.

The story was about an airplane that flew through some kind of portal or vortex while the passengers were asleep. When they woke up, everyone else on the plane was gone. They landed in a world which looked like the normal world except there were no people. The world appeared as kind of drab, colorless, lifeless, but I'm not sure about that. One of the cast was a blind girl, about middle school age.

Eventually, some kind of monster appeared, which was depicted (pretty cheesily) as a big floating pac-man looking thing that ate the people. Eventually they realized they had to get back on the plane and fly back through the portal while they were sleeping. Except the pilot offered to stay awake to pilot them into the portal, and then he died or went off to where everyone else disappeared to.

Rough estimate of time was the 1990s.
