A Cape Air official has apologised to the customers on Saipan in the Northern Marianas, saying disruptions will end and services will be back to normal soon.
The US carrier, Cape Air, has only one aircraft operating its Guam-CNMI route, with many flights reported cancelled over the last months.
Cape Air's vice president for planning, Andrew Bonney, says one of its ATR42 aircraft is under scheduled maintenance while another ATR is due for maintenance in the first quarter of 2015.
He points out that when both its planes in the CNMI are operational, Cape Air has one of the world's highest completion rates.
Completion rate is the percentage of scheduled flights completed.
Mr Bonney says adding a third plane to their Guam-CNMI route would result in an increase of fares by 28 US dollars.
