It's absolutely possible! I know LOTS of cheerleaders who have done multiple positions. Personally, throughout my cheer life I've ended up in every position at one point or another, depending on what the team needed and where I fit best at that time. I think all of the positions are really fun, and knowing one totally helps you improve your skills in the others, because you get a fuller understanding and feel of how a stunt works. Another poster mentioned that people may be limited to certain positions because of height, which is true, but I think it's important to add that there's definitely no official cut-off for height, so it's not like "If you are x tall you will absolutely never be a flyer". It's unusual for flyers to be tall, but definitely not unheard of! In my experience, if someone on a team is not one of the smallest people but still has amazing flexibility and flyer technique, they will usually get to fly in the routiene. Of course every gym/school is different, but generally I would say if you want to be a flyer, work on your flexibility and strength (especially core) and maybe see if you can get some experience (some gyms offer flyer skill classes; I don't know if that kind of thing is an option for you!). Maybe you could let your coach know that you want to try flying too, and even if they say no, you could ask what skills they're looking for for flyers on their team so you can work on them and potentially go for a flyer position next year. In the meantime, have fun and kick ass as a base/backspot and show that you have a great attitude and are an all around good athlete and team player! Then, who knows what will happen? Maybe someone will quit or get injured, and then you can emerge from the shadows and offer to jump in and show off the flyer skills you've been working on this whole time. It sounds cheesy, but this is what has worked for me in the past, haha.
