National Airlines serves major metropolitan cities throughout the U.S., particularly those that serve as international gateways. National offers nonstop flights to and from its Las Vegas hub.
Airlines have many fares between any two cities.
Some of these fares have a number of restrictions, others a few restrictions, and some have no restrictions. If the fare you are now being quoted is higher, then it is likely that the lower fare seats were sold to other customers between the time you were originally quoted the fare and now. Even if you made a reservation, the quoted fare is not guaranteed until you make your purchase. Also, it is important to remember that tickets purchased through our Web site may often be lower priced than tickets purchased elsewhere. Where We Fly page.
