How old do i have to be to travel from UK to Canada or Crete?

Im 15 now and 16 in a month + I want to know how old I have to be to travel to Crete or Canada with my best mate whose the same age. We want to travel in the summer.

15 sounds a fine age to me I did it at 14 and I'm now 15

yeah you should be ok

18 - you can fly at any age with parents permission but you need to be 18 to book the hotel. I guess you could go if you're parents or you're friends parents booked the hotel on their credit cards for you.

Ask a travel agent how you should go about it - they'll be more than happy to help.
