Christian Noriega of Hayward Calif., with an umbrella on his side checks in at the Philadelphia International Airport Monday, June 13, 2011, in Philadelphia. Noriega said he spent about $163 to check three bags with American Airlines. The government says that airlines collected $3.4 billion in baggage fees last year, up 24 percent from 2009.

The FBI says a flight bound for Dallas has returned to Philadelphia after law enforcement officials received a tip that liquid explosives could be on board.

FBI spokesman Frank Burton says US Airways Flight 1267 was called back to Philadelphia International Airport after officials received the anonymous tip.

Passengers were removed from the plane and bused away as law enforcement vehicles surrounded the aircraft. Video from TV stations showed law enforcement officials removing a person from the flight and police dogs on the tarmac.

Airport spokeswoman Victoria Lupica says there were 69 passengers and five crew members on board. She says no other flights have been affected by the activity.

The flight was headed for Dallas-Fort Worth International Airport.
