I don't know much about flying. Maybe its b/c I haven't flown since I was 5 but now that I have to for interviews I don't know which airlines I should choose. Which airlines are considered good. I went to Expedia.com and they give me many diff. options. Should I just buy the cheapest fare. America West and US Airways are cheaper than American and United. Is it b/c American and United are better? Can anyone suggest what I should do?
