20 years old is not too young to be flying..i started when i was 17...now 21 with CPL...etc..
Last night at a party i met a friend of mine i havnt seen in ages. The reason i hadnt seen him was because at the age of 20 an airline picked him up, he is now flying J41's at the age of 21.
Age is just a number, its all up to you! :-)
