Figureing out what airport to use

Hi, I am having some trouble getting my tickets because I do not know which airport to use. Yesterday I did open a high interest checking account and put my money for my trip in it. I will get like 130.00$ because I opened it! Yea! I have not received my final loan for my trip but should soon. Also I need to figure out what to pack, so that is what I am doing right now.
