Your dream and mine. I know that you usually have to relocate to one of the airlines major hubs. And, you're probably on call for 20 days a month. I think with most airlines, you have to be at least 21. I figured at 31, I'm too old. But, I read a book recently (true story) and the author mentioned that his wife had always wanted to be a flight attendant. So, after the kids were in college, she did it -- she was in her 40's. That gave me hope!
I currently have my ultimate dream job of a 911 dispatcher and was 28 when I landed that. So, maybe there's hope for me to live my other dream jobs still! Good luck! Funny, two college degrees and I'm out living my dream jobs that all you need is a high school diploma for. (EMT & communications officer.)
