Why did Dorothy and Sophia take a plane to Disney World when it's a three hour drive from Miami, and Dorothy hates flying?
She was going to drive, but Rose threatened to join them and sing "Ninety-Nine Bottles of Beer on the Wall" for the duration of the ride.
And they took the "red eye" to LA for grab that doe. There are no red eyes in the east-west direction. Did they not think we knew that???
Dough. One does not grab a doe on television.
As for the compelling plane question, there really wasn't a plane at all. It's just a story, dear. There is no reason to worry about it a quarter of a century later.
