FYI to ANYONE who plans to travel via airline - DO NOT GO WITH US AIR - US Air has extremely terrible customer service. They also have the worst policies of all airlines compared to one another.
Delta airline is now offering DIRECT flights to Mexico for amounts that are CHEAPER than connecting flights to Mexico that US Air airlines has.
Furthermore, Delta has much friendlier customer service as well as least restrictive policies. If you do not like Delta, find another airline but take my word for it, DO NOT choose US Air airlines, it would be a large mistake and you will end up unhappy.
Monetary Loss: $1600.
