Airplanes are probably the most expensive way to travel, but discounts are possible for advance reservations. You may contact individual airlines (call or check their websites) or contact a travel agency. A travel agency will assist you in making arrangements for your ticket and provide access to many different airlines at once. Airlines are listed in the telephone book in the yellow pages under "Airline Companies". Travel agencies may also be found in the yellow pages under "Travel Agencies and Bureaus" or "Airline Ticket Agencies".
