White is white
A white Airbus A319, owned and operated by the Portuguese company WHITE AIRWAYS, S.A., often seen in Geneva.
Since the end of August this white Airbus A319 is often seen flying between Geneva and various European destinations. The aircraft, with registration CS-TQJ, is owned by the Portuguese company WHITE AIRWAYS, S.A., and is described on the company's web site as one of its three executive Airbus 319 CJ aircraft.
The CJ description is short for Corporate Jet, of which Airbus offers different versions. According to Wikipedia, it incorporates removable extra fuel tanks which are installed in the cargo compartment, and an increased service ceiling of 12,000 m (41,000') giving a range of 6,500 nautical miles (12,000 km). It is described as the Airbus alternative to the Boeing Business Jets (BBJs). In its basic configuration it seats between 19 and 50 passengers but may be outfitted by the customers into any configuration.
A look at the images for the aircraft on the site of the operator suggests that the highly luxurious configuration is likely to be at the lower end of the seating, or lying, scale. Not surprisingly, the very luxurious seats, which convert to beds, are in white leather.
As is usual, the flights of aircraft such as these are never mentioned on the airport arrivals and departures information board. However, the flight tracking web sites can show their movements. The most recent departure, the afternoon of 8 September, shows the aircraft taking off over the lake then flying as far as Yvoire before making a wide 180° U-turn over Gland to head back towards the Iberian Peninsula. No doubt the passengers, sipping their aperitifs, would have enjoyed the sunny views, whilst the airline clearly had no need to worry about being economical on fuel and getting to the destination as soon as possible.
Obviously, there is enough money around for such flights, though I doubt if the Geneva State executive would be using them!
