I dis like US , recently flew on a 2:45 flight from phx-iah and was served no meal ( they start at 3 and a half hours or longer ) and plastic cups throughout. A very stingy airline ,
IMO UA has the most bang for your buck when it comes to miles. Especially for F awards , but If I had to go , AA would be my pick . Good service , nice F product and good mileage availability.
