A Frontier Airlines Airbus A320neo aircraft was subjected to a security inspection at Washington Dulles International Airport on April 9, following reports of a beeping noise originating from the cargo hold. The incident occurred after the flight arrived from Hartsfield-Jackson Atlanta International Airport. The plane was initially parked away from the main terminal to facilitate a thorough inspection.
Flight 4708, which had a scheduled departure time of 12:43 and an expected arrival at 14:29, landed at 14:36 according to data from Flightradar24. Passengers were evacuated while authorities conducted the security check. The aircraft was eventually cleared and returned to operation by approximately 16:45. Frontier Airlines confirmed in a statement, “The aircraft and all passenger baggage has been cleared. Passengers have been reunited with their bags and the aircraft has been returned to operation.”
The Airbus A320neo involved, registered as N363FR, has been part of Frontier's fleet since November 2019. The plane, with a capacity for 186 passengers, is 5.43 years old.
