Earlier, the curbs were in place only for non-scheduled flights with certain exceptions.
From January 19 to 26, no flights would be arriving or departing from the Delhi airport between 10:20 am to 12:45 pm, the official said on Friday.
Generally, a NOTAM (Notice to Airmen) is a notice with information that is essential to personnel involved in flight operations.
