Every time I fly, I choose American Airlines. Even though I'm 19, I have 30,000 miles in my American Advantage Account. The staff is very kind and helpful. I took a study abroad last summer and flew through one of their sister airlines and I was able to easily transfer the miles to my American Airlines Account. I have the iPhone app so it is easy to see my boarding ticket, my miles, account information, and any delays my flight may have! I would definitely recommend American Airlines to anyone who needs to book airline tickets!
