DALLAS » American Airlines says a man training to become a flight attendant was dismissed after he was accused of making bomb threats against another airline and found to be on a government no-fly list.

The airline said today that the man began training in April in Fort Worth and was fired in May. The airline says he’s accused of making threats against United Airlines flights.

American Airlines spokesman Matt Miller says the airline checked the man for any criminal record and whether he was on the no-fly list, but nothing turned up.

Miller says his understanding is that the man was added to the no-fly list after American conducted its background check.

The airline isn’t identifying the man.
