Hoping to go travelling for a year+ in March

Have looked on statravel.com and their is a youth card that gets money off everything if you are under 26

I will be 26 in the January so does that count me out, also if I get one just before im 26 will it still be valid. (before you say I have tried calling them but no answer)

Anyone know any other year ticket round the world flight deals that are about, or any helpful websites

Regards

Paul
