Airline ticket An airline ticket is a document or electronic record, issued by an airline or a travel agency, that confirms that an individual is entitled to a seat on a flight on an aircraft. The airline ticket may be one of two types: a "paper ticket", which comprises coupons or vouchers; and an electronic ticket (commonly referred to as an "e-ticket").
AOG desk An AOG desk is a dedicated aviation logistics service. The principal aim of AOG desk personnel is to obtain the supply of components or services for aircraft in an AOG (“aircraft on ground”) situation (i.e., in emergency situations where aircraft are grounded due to technical failures) in the shortest possible time. Every airline has an AOG desk—a vital requirement to reduce technical delays. It is estimated that an AOG can cost an airline $150,000 per hour. Nearly every supplier in the aviation industry (OEM, distributors, parts dealers, and brokers) also maintains an AOG Desk to service calls from airlines searching for critical parts.
