less than seven months in 2005, but said the service was "not as profitable as we had hoped". In 2008, after a few years of service from Chubu Centrair, several airlines cancelled certain flights and put others on hiatus, including Malaysia Airlines' suspension of flight to Kuala Lumpur, Jetstar ending its airport operation, Continental Airlines stopping its Honolulu flight and United Airlines' suspension of flights to San Francisco, citing low premium cabin demand.

Japan Airlines also ended its flights to Paris in 2009 and Bangkok in 2020. Garuda Indonesia ended service from Denpasar in March 2012, but returned to Nagoya with the opening of direct flights from Jakarta in March 2019 but only lasted until March 2020. EVA Air left the airport in June 2012 (they have since planned to resume service from June 2019). TransAsia Airways subsidiary V Air withdrew from Centrair and ended operations in October 2016.
