Other mistake: Tower Air never had direct flight service to Boston, only to NY from LA.
Other mistake: When Fletcher is attempting to force himself to write the word "red" on his desk, in the shot before the "blue" is revealed, his pen is not even touching the desk and his final pen movement is a curve which doesn't correspond to an exclamation point.
Suggested correction: He had already finished writing "blue!" by the time we see the shot of him holding the pen off the desk. He was probably making the motion of writing "red" (with the curve you see corresponding to the "d") not realizing that the pen wasn't touching the desk, and not realizing that he had already finished writing "blue." Hence his initial gleeful reaction-he thinks he's successfully beat the spell, until he sees the writing and realises he hasn't.
