Decoding 4312458912345 ALLEGIANT AIR
Unreviewed registry note: A billing descriptor showing 4312458912345 ALLEGIANT AIR corresponds to an airline ticket or an ancillary travel service purchased through Allegiant Travel Company. Allegiant Air is an ultra-low-cost American carrier that connects regional communities to vacation destinations like Las Vegas and Orlando. The long number preceding the airline name is the passenger ticket document number, where the leading digits 431 represent the official three-digit airline accounting code assigned to Allegiant by the International Air Transport Association (IATA).
Unreviewed registry note: Because Allegiant operates on an unbundled fare structure, an initial booking covers only basic seat transportation and a small personal item. Extra choices you make during checkout or at the airport terminal post under this same merchant descriptor. Routine charges include checked bag fees, carry-on allowances, seat assignments, Priority Boarding, and the Trip Flex travel protection add-on. If you purchased an Allegiant vacation package that combined airfare with a hotel stay, the entire bundle clears under this merchant descriptor.
Unreviewed registry note: If this charge caught you off guard, check your email accounts for a flight confirmation message from allegiantair.com. Airline charges can also appear when a family member books a trip using your payment card, or when an existing reservation incurs a modification fee. You can verify the transaction by visiting allegiantair.com/manage-travel and entering the passenger last name along with the six-character confirmation code. The website will display an itemized breakdown of airfare and add-on fees.
