I don’t know if it’s the least frequent, but LATAM offers flights once a month between Santiago and Mount Pleasant (on the Falklands) via Punta Arenas and Rio Gallegos. The outbound flight (to the Falklands) is flight LA897 operating on the second Saturday of the month, and the return flight is flight LA896 operating on the third Saturday of the month.
On the other Saturdays, LA895 (outbound) and LA894 (return) operate the same route, except without the stop in Rio Gallegos. So the RGL-MPN leg in each direction is only run once a month.
The reason is that flights are allowed under an agreement between the British and Argentine governments in 1999. The British did not want any direct flights from the Falklands to Argentina, only to Chile; the Chileans and Argentines did not want a flight without a stop in Argentina. This was the compromise, see http://www.nytimes.com/1999/07/15/world/britain-and-argentina-to-allow-commercial-falkland-flights.html.
My understanding is that technically, you can’t have a scheduled flight less than once a week, because airline schedules are published in a weekly format:
MH172 KUL0850 – 1200DEL 738 245
MH190 KUL1850 – 2150DEL 738 134
The last number in each row is the days of the week when the flight operates, from 1 = Monday to 7 = Sunday.
The only way to schedule a flight less than once a week would be to start and stop it every week when it flies, which is (again, technically) indistinguishable from a seasonal or chartered flight.
