 The new company will have a nine-member board, with Qantas CEO Geoff Dixon slated to be chairman.
Air transport in the United Kingdom is the commercial carriage of passengers, freight and mail by aircraft, both within the United Kingdom (UK) and between the UK and the rest of the world.
 In the past 25 years the industry has seen continuous growth, and the demand for passenger air travel in particular is forecast to increase from the current level of 236 million passengers to 465 million in 2030.
 One airport, London Heathrow Airport, is amongst the top ten busiest airports in the world.
 More than half of all passengers travelling by air in the UK currently travel via the five London area airports.
 Outside of London, Manchester Airport is by far the largest and busiest of the remaining airports, acting as a hub for the 20 million or so people who live within a two-hour drive.
 Regional airports have experienced the most growth in recent years, due to the success of 'no-frills' airlines over the last decade.
Jetstar Asia's first flight took off on 13 December 2004 to Hong Kong, one of the two initial destinations from Singapore.
 Jetstar Asia was established six months after Jetstar Airways first commenced its domestic operation in Australia.

In the airline and travel industries, a passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that consists of the personal information for a passenger and also contains the itinerary for the passenger, or a group of passengers travelling together.
 The concept of a PNR was first introduced by airlines that needed to exchange reservation information in case passengers required flights of multiple airlines to reach their destination (“interlining”).
 For this purpose, IATA and ATA defined standards for interline messaging of PNR and other data through the "ATA/IATA Reservations Interline Message Procedures - Passenger" (AIRIMP).
 There is no general industry standard for the layout and content of a PNR.
 In practice, each CRS or hosting system has its own proprietary standards, although common industry needs, including the need to map PNR data easily to AIRIMP messages, has resulted in many general similarities in data content and format between all of the major systems.
