Tehran’s Mehrabad and Khomeini airports—alongside airports in the north, south, east, and west—are now operational and ready to serve both domestic and international traffic, according to the statement.
"From July 4, all airports except Isfahan and Tabriz will host daily flights between 5 a.m. and 6 p.m.," read the statement.
The skies over central and western Iran are also reopened during this window for international overflights, the statement added.
Eastern airspace, the organization said, remains open around the clock. Airports in the east continue to operate 24/7 under previous schedules.
The Civil Aviation Organization added that Isfahan and Tabriz airports will resume operations once infrastructure is restored and no further restrictions are in place.
The country closed its airspace on June 13 following Israeli airstrikes on Tehran and other areas. After a 12-day aerial conflict, the two countries achieved a ceasefire on June 24.
