Im British staying in USA, can I use my British Driving License for ID to travel?

Can I use my british driving license as proof of ID to travel on domestic flights within the US? or do you have to have an American Driving License?

Your British one will probably do, but why don't you just use your passport? You must have one if you are from the UK and I would assume you would be bringing with you while you travel (if not then I would recommend you do so).

As the US has such strict security nowadays, I believe that a valid passport will be the only form of ID that will be accepted if you wish to travel within the US.

Use your British passport
