A Pittsburgh-bound flight from Punta Cana had to be diverted to Florida after four crew members and three passengers were injured from unexpected turbulence.

Some passengers were tossed from their seats, and one flight attendant hit her head on the ceiling of the Allegiant Airlines flight on Thursday.

The flight from the Dominican Republic hit the turbulence over the Bahamas, and the plane was diverted to Fort Lauderdale-Hollywood International Airport.

The airline says the charter flight operated for Apple Vacations had 137 passengers and six crew members.

The Broward County sheriff's office says the injuries weren't life-threatening. The most seriously hurt was a flight attendant who had head injuries.

The airline arranged other flights for the passengers, but some opted to drive home.
