The immigration authorities of many countries require all airlines to provide passenger passport information prior to departure of any inbound or outbound flights to ensure safety and security. Currently these countries include:
Passengers travelling to the UAE from certain countries also need to provide Advance Passenger Information. Currently these countries include: Iran, Iraq, Pakistan and Yemen.
If you are travelling to one of these countries, you can still use online check-in where available, provided that all of the relevant passport information for you and anyone travelling with you has been completed. If any passport information is missing or incorrect, you can add or edit that information through the online check-in system.
Please note that all travel in such instances is subject to the approval of immigration authorities in the destination country.
