How easy is it to deal with money and banking in Chile?

Hi,

I think I can provide you some info. I am chilean even though I am living in Ireland now. Yes, you can get money exchanged at the airport but usually at high rates. The airport is quite small and usually crowded and not really safe to get the money there. I would recommend you getting money (chilean pesos) before you move there. Some cash for taxis, food, etc. You can pay with cards but not in all places. 

I don't think that opening a bank account is necessary, but it will depend on what kind of expenses you will have or how long is your staying. I'd say that using a credit card would be enough. The commission for getting money from your bank account is quite high, from U$6 to U$8 each time so I would recommend getting some cash for small things but not too often. 

I hope that helps you. Any other questions, feel free to ask.
