You will need to ensure that the name you have registered with, matches that in your passport. For example, make sure that you have not listed yourself as "Sam" if the name in your passport is "Samuel". You will need to make sure your passport is valid for at least six months from your return date. If you have renewed your passport then you will need to provide us with your new passport number.
You may also need to make sure you have the valid Visa for the country you are traveling to. Please refer to your Briefing Pack for Visa information.
