The suspicious package on the plane was re-screened and cleared by security officials, according to the TSA (Transportation Security Administration).
In a press statement, the TSA said that the checked bag was re-screened at Logan after baggage handlers in Philadelphia "noted concern." The plane landed safely at Logan and passengers were bused to the gate.
"While properly screened by TSA at Philadelphia International Airport (PHL), the bag was re-screened by local EOD (Explosive Ordnance Disposal team) at BOS as a precaution and has been cleared," the statement said.
Massport also released a statement saying the flight was remotely parked on the runway while the bag was re-screened "out of an abundance of caution ... the baggage was deemed harmless, and the flight taxied to the gate. Airport operations were not impacted."
