Two passengers on American Airlines flight AA1655 from Philadelphia to Boston apparently didn’t like their boarding group. Instead of waiting for the official boarding call, two hours prior to flight they “walked on board through the doorway to the jet bridge and took their seats.”
The pair were discovered during the boarding process. They were on the correct flight, and in the correct seats. But the plane was offloaded. The aircraft was searched. And American decided to swap planes anyway before proceeding with the delayed flight.
