Airline spokeswoman Andrea Huguely says Flight 160 landed in Orlando late Tuesday after the pilot's double-paned windshield cracked while the plane was in flight.
Huguely says a cracked windshield "doesn't happen a lot, but it does happen on occasion." It wasn't immediately clear what caused the crack.
The plane landed in Orlando with 156 passengers and crew members on board. No injuries were reported.
Huguely says the passengers boarded another aircraft that landed in Boston early Wednesday. The aircraft with the cracked windshield was pulled out of service for repairs.
