Advance Passenger Information

We recommend online check-in for all flights, even if you are going to check in bags at the airport. To check in online, you must also fill in the Advanced Passenger Information (API) form. This is mandatory information which the authorities require before the date of travel, and the airline is responsible for collecting it. Even if you intend to check in at the airport, you should still fill in the API form online in advance.

The API form requests all or some of the following information:

  • Full name (first, middle and last names) exactly as it appears on your passport
  • Date of birth
  • Gender
  • Passport number and country of issue
  • Passport expiry date
  • Nationality

If you are travelling to or from the USA, you will also need to provide the following:

  • Your address in the USA for the first night of your stay (except for citizens and residents of the USA)
  • Your redress number (if applicable). The redress number is a reference number issued by the US Department of Homeland Security to travellers who have previously experienced difficulties obtaining entry to the USA.
