Cayman Airways took possession of a new Saab 340 aircraft in August that will service the route between Grand Cayman and Cayman Brac.
The plane replaces the Embraer 120 aircraft, which was leased by the airline for an interim period while the purchase of the Saab was finalized.
The new plane will touch down at Owen Roberts International Airport at 12:30 p.m.
Government and airline officials will be in attendance at the airport for the arrival of the aircraft and invited guests will tour the new plane.
The leased 30-seater Embraer has been in operation between Grand Cayman and Cayman Brac since October last year.
