I recently heard that from a Delta Captain and couldn't believe it. Every other airline I know of gives you at least two chances to make an upgrade. He told me he knows of a 28 year old pilot who will be an F/O at Delta for life because he took an early upgrade and failed.

Not that you're worried about that, but it is something to factor in.
