I'm planning a trip to Ann Arbor to visit my best friend. I think I'm making it more complicated than it really is. The cheapest ticket I can find is $188 round trip on Northwest, which isn't too bad. Except there are so many different flight times. There are all of these different things to consider. And I want to make absolutely sure that the days I'm planning on being there are good for my friend. I thnk the problem is that I've never travelled by myself. My mom has always handled the whole ticket thing. But I think I've picked out a good flight time, and I'll stay for five days. I just have to buy the ticket now. But it's non-refundable, so I don't want to make a mistake.
