Flying from Alberta to Phoenix (approx 5 hr layover, 9am-2:00pm - should we just hang at the airport or leave for a few hours?)
Then we arrive Maui at 5:00pm. So my real question is... how is it flying with US Airways? We haven't flown with them before. We're flying using Airmiles (economy) but how accommodating are they for us to purchase upgraded seats and what do they normally charge if business class is available at point of check in?
