5. Airport/Aircraft/Flight Identification

Sample Luggage Tag A. Bar codes contain four characters signifying the final destination. B. Carrier initials (Speedy Flight) and a six-character bag number are followed by a three-character abbreviation for the final destination (FWA = Fort Wayne, Indiana). C. Final flight listed first, carrier initials, flight numbers, and date for all parts of the journey show a mini-itinerary. Destinations for initial flights are listed in smaller type (DTW = Detroit, Michigan).

All airports have an airport identifier. The identifier is actually four letters or a combination of letters andnumbers. Since the first letter of all continental United States airports is "K", it is just omittedfrom the remaining identification letters. If you have flown into any of the destination airports listed belowyou might recognize the three-letter airport identifier that is also found on the luggage tag.

DEN Denver International
MCI Kansas City International
STL Lambert-St. Louis International
CLE Cleveland-Hopkins International

Cars have license numbersand airplanes have registrations commonly called "tail numbers." All aircraft registrations begin witha letter followed by more letters, or a letter followed by a number. Aircraft registered in Canada have a "C"followed by a hyphen with 3 additional letters. So an aircraft registered in Canada could be "C-DOG."Aircraft registered in Mexico have registrations that start with "XA," "XB," or "ZC"followed by a hyphen then three additional letters.

"N" is the beginning letter for all aircraft registered in the United States. During verbal radio communicationsthe complete U.S. registration is given on first contact with air traffic controllers. Usually in subsequent communicationsonly the last three numerals or numeral and letter combinations are used.

Let's take, for example, a Grumman American TR-2, a small aircraft, registered as N9919F. "N" indicatesaircraft registration in the United States. When it is verbally identified to air traffic control (ATC) it is notidentified as "N - 9 - 9 - 1 - 9 - F." The correct way to identify the aircraft N9919F is "GrummanAmerican, November niner - niner - one - niner - Foxtrot." After the initial contact with air traffic control,it is then shortened in verbal communication to "one - niner - Foxtrot". If a controller is working twoaircraft with the same last three tail numbers, the controller will use the complete registration.

Commercial airliners usually use the airline's name followed by the flight number. For example, "United AirlinesFlight 1291" would be listed as UAL 1291 on the routing strip used by controllers while spoken as "United- one - two - niner - one".
