Baghdad International Airport has been re-opened - after a dispute with foreign contractors over payment for security services closed it on Friday.
The road to the airport often comes under attack
"We have reached agreement...the airport is now open for domestic and international flights," the acting transport minister told AP news agency.
A UK-based firm has been providing security at the complex which lies 18km (12 miles) from central Baghdad.
It halted operations on Friday, saying it had not been paid since March.
Global was given a contract by the US State Department in 2004 to provide security at the airport.
A spokesman for Global in London, Giles Morgan, told AFP news agency its personnel were back in position as the Iraqi government had "agreed to pay 50% of the total money owed for the past seven months."
The airport was closed for two days for the same reason in June.
