Hello lfennah, API registering only applies to some countries, and can be done in advance if your holiday is no less than 7 days away. If your holiday is less than 7 days away, you can easily provide this information at check-in where a member of staff will explain it to you.Kind regardsJames, your editor

Hi

Someone has mentioned to me that I need to register API (advanced passenger information) with the airline. I haven't heard of this before. Can you please advise if I need to do this before I check in. If so how do I go about it? I am flying with Monarch Airlines next week.

Regards

Lynne
