I'm thinking of flying from las vegas to austin or dallas is unusually cheap.
Why do you want to go there?
It is so expensive at home and I can't breath in Sweden.
It is good to consider your finances when planning a trip. You don't want to spend more than what you can afford to spend and then have no money for things you need.
I'm just gonna make youtube videos and make a living there doing that.
It seems like you have a plan and it is good that you at least considered costs for the trip. At least it will help you have some money while you get established there.
