Turkish Airlines warned in a statement "the number of cancellations is likely to increase" because of the weather conditions.
The operator of Istanbul airport, Europe's busiest last year, did not respond to requests for comment.
It was the first time the airport shut down since its inauguration in 2019 and the operator was criticised over the management of the crisis.
Hundreds of passengers were stuck at the airport, unable to fly or return to the city because the roads were blocked by snow.
The airport had been criticised before it opened for alleged environmental destruction, a lack of good transport links and the choice to build it close to the Black Sea where there is often thick fog in winter.
