Im 16 but will they allow me to fly if i dont have any kind of id(but i do have my birth certificate)??

If you're a minor you don't need an ID. They will ask questions to confirm your identity.

Check with the airline and TSA, you can check their websites.

They let my son fly with birth very, you may want to contact the airline that you're flying and ask them what their policy is? Because you may need a letter along either that birth certificate from an adult giving permission for ya to fly cuz they may I have a policy in place that keeps them from being liable if something were to happen to a miner I would just call the airline,

Best check with TSA online or any other possible way

Best to check directly with airline & TSA websites.
