Authorities later discovered that the person implicated on the tip call was on the flight to Dallas that had departed at 7:39 a.m. and ordered it to return, according to ABC News' Philadelphia affiliate WPVI.
The man was being questioned, his luggage was searched and no explosives were found. No explosives were found on the plane.
All 69 passengers and five crew members on flight 1267 are safe.
"As soon as we had the situation on the plane secure, I did speak to all the passengers and they were briefed as to what was going on," Sullivan said. "All the passengers were extremely cooperative and very understanding, despite the fact that they were all shaken up."
Philadelphia police officers, FBI bomb technicians and SWAT officers boarded the plane once it had landed and was moved to a safe location. The flight was deemed safe and able to depart for its destination.
"It was a hoax all the way through," one official involved in the investigation told ABC News.
