Cornwall Airport Newquay had previously shut its doors to travellers on 9 November due to a lack of demand before reopening on 18 December.
On Twitter it said its terminal had now “temporarily closed” with commercial flights “currently suspended”.
Flights to Heathrow, Leeds-Bradford and Manchester were expected to restart on 12 February, its website said.
The next flights were not listed until mid-March, the website also said.
The airport said its website had the most up-to-date information from airlines but it was “subject to change”.
All other aerodrome services at the site, including supporting emergency services, training and military flights, were still operating, managing director Pete Downes said.
He said that work to rebuild routes and services after the collapse of the airport’s former main carrier, Flybe, last March was also continuing, and “much of that” was due to “come into effect in March”.
He added: “We’re confident that traffic and demand will be returning.”
