PITTSBURGH - A US Airways flight headed to Phoenix made an emergency landing in Pittsburgh after a dog on board bit a passenger and a flight attendant.

US Airways spokesman Todd Lehmacher says the flight left Newark, N.J., on Monday morning. Lehmacher says a passenger carrying a dog let the animal out of its carrier and it bit a passenger and flight attendant.

The severity of the bites was not known. Lehmacher says the pilot decided to land in Pittsburgh to make sure everyone was OK.

Lehmacher says the airline hoped to get the passengers to Phoenix as soon as possible.

Lehmacher says US Airways allows passengers to carry certain pets if they are secured in approved carriers and kept under their seats.
