"While martyrdom in the manner of Eastern Airlines is one option, I do not believe that the majority of our pilots would prefer to embark upon a path of self-destruction in order to make a political point or poke management in the eye," he wrote.
Wilson, who has said he voted against the company's August offer, said the deal now before pilots is much better.
Robert Mann, an aviation-industry consultant who once worked at American, said Wilson's comments seemed reasonable and aimed at overcoming a "toxic lack of regard for and mistrust of the AMR management team" among rank-and-file pilots.
American declined to comment.
Unions for American's pilots, flight attendants and mechanics support a takeover of AMR by US Airways Group Inc., and agreed on conditional contracts with US Airways. The companies have been talking about a potential merger for two months, but signs indicate that AMR prefers to emerge from bankruptcy protection on its own.
