No. You cannot fly from Erbil to Baghdad with only a Kurdistan visa. A visa or entry permit issued by the Kurdistan Regional Government is valid only within the Kurdistan Region, which covers Erbil, Sulaymaniyah, and Duhok. Baghdad is located in federal Iraq and operates under federal immigration authority. A regional Kurdistan permit does not give you permission to enter federal Iraq.
Domestic flights and boarding checks
Commercial domestic flights between Erbil International Airport and Baghdad International Airport connect two separate immigration jurisdictions. Airlines check travel documents before boarding in Erbil. Federal immigration and security officers inspect arriving passengers at Baghdad International Airport. If you only hold a Kurdistan regional visa, the airline in Erbil will refuse boarding. If you reach Baghdad without an approved federal visa, authorities will stop you at airport control. Entering federal territory without a federal visa violates Iraqi immigration law.
Obtaining the required federal visa
To fly from Erbil to Baghdad, you must obtain an approved federal Iraq visa before you travel. You can apply through the official Iraqi Electronic Visa Portal at least 24 hours before departure if your nationality is eligible. Travellers who cannot use the online portal must apply through an Iraqi diplomatic mission, such as the Embassy of the Republic of Iraq in Washington, D.C..
