In commercial aviation, what is the system where in-flight food or beverages are able to be purchases after being issue the document or electronic record by the airline?
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").
Airborne Internet Airborne Internet can provide an interconnected digital data network between aircraft, and between aircraft and the ground. It has the potential to change how aircraft are monitored and tracked by the air traffic control system, and how they exchange information with and about other aircraft. Critical information such as weather, turbulence, and landing conditions can be transferred, as well as the distance between aircraft. This information becomes even more critical for aircraft that are beyond the range of conventional surveillance radar. There would also be the capability to allow aircraft passengers to go 'on-line' to check their e-mail, pay bills and surf the web.
