Hey Becky,
Some airliners have a minimum age in terms of being an employee with them. This can vary but I think it's in the region of low 20's to mid-20's.
I think going to University or equivilant to gain a degree etc... will put you in good stead and increase your prospects of sitting in a nose of a plane!
Having said that, yes, indeed I think you should definately continue with your ATPL studies. In my view, this being number one priority.
Remember - 'Work hard, play hardER'
Good luck....
Rob
