Hi there! I AM a travel agent. I have been for 13 years. You don't need a license, but you need schooling and training. The best experiance however is "hands on" by working in an agency.
Things in this business change every day. You have to be an organized person who can handle stress well. You wouldn't think it would be a stressful job, but believe me it is. Also, the pay is not the best, so don't get into this job for the money. If you have any specific questions you can PM me. Good luck with whatever you choose!
