Planes at Cape Air were grounded briefly on Sunday after a bomb threat was phoned in and later found to be a hoax.
Michelle Haynes, a spokeswoman for the Cape Cod airline, said Sunday the call came in on the airline's 800 number Saturday and was taken by an employee in Maine.
Haynes says the airline's Cessna 402 planes are small, with 10 seats, making inspections relatively easy. No explosives were found.
She called it a rather quick event to take care of and disruptions were minimal.
Haynes says the call came in at 5:25 p.m. and planes were back in the air by 7 p.m.
The FBI is investigating.
The commuter airline has flights along the East Coast, Virgin Islands, Guam and elsewhere.
