As I have promissed you in my last article, I wanted to make the stracture of this note a little bit easier for you. It would be better to write it in english...wherever will you go. Also it would be nice to have with you a birth certificate...So, let's see how should this note look like
You should check out your airline, or even ask them what should I need to travel alone. So, here's what Aegean Airlines require
I am the parent/guardian of the child mentioned below and herewith give permission to him/her to travel unaccompanied. I confirm that I have arranged for the child mentioned below to be escorted on departure and on arrival by the persons named: the escort on departure will remain at the airport until the flight has departed. Escort on arrival must present an identity document with photo and will be available at the airport at the scheduled time of arrival of the flight. I furthermore declare to indemnify and hold Aegean Airlines and/or other carriers, their personnel and agents for and against loss or damage sustained, cost and expenses incurred by them in connection with the child’s travel or resulting therefrom, and to release them form all liability other that set forth in their general conditions of carriage. Should the child not be met as stated below I understand that Aegean Airlines and/or other carriers concerned reserve the right to take whatever action they consider necessary to ensure the child’s safe custody and that such action might include returning the child to the airport of departure. I also confirm that the child is in possession of a valid passport and has necessary visa(s) for the entire journey.
