You've got until you're at least 35, possibly 40 in some cases, in order to make it onto one of these airline programmes. So, the best bet is to keep applying, remember, other programmes will likely open in the near future. Make sure you get feedback from your application with Easyjet and find out when you can next apply for one of the L3 programmes with another airline.
In the meantime, look for a career outside of aviation that you'd be happy in.
