US Airways / America West Airlines Official Website Makes it Easy to Book Reservations: US Airways and America West Airlines official site is a great site to make reservations for specific flights on this airline. I like this site because you can easily see the routes the airline flies and enter specific departure and arrival airports and dates to see a list of all available flights which can be sorted by price, layovers, it will even provide alternate flights if your travel dates are flexible. Frequent fliers can also make reservations from this site by using their accumulated miles and can get real time accounting of the miles that they currently hold in their account and what remains after booking. I really like the fact that a traveler can see all options for departure and return flights on one page and do not have to toggle back and forth which can get very confusing. I can even see the available seats on the plane to determine how crowded the flight is and whether my travel companion will be able to sit next to me. I can't find anything negative about the site, every question that I need answered regarding my flight can easily be found here
