MSN.com is reporting a "sharp rise in demand" for private jet business between the U.S. and London after recent terror alerts. 

Some of the sources noted in the article include: Aviation Research Group, Delta AirElite, Sentient, DayJet, NetJets, and Gulfstream.

One of the more interesting financial tidbits from the article is that you can now purchase a "10-hour jet card in the $41K range." And that the ultimate goal for a service provider like DayJet is to get to the "$1 per mile per seat cost model by the end of 2006" to bring private jet travel out of executive circles and down to middle management.

An upgrade so to speak from jet cards is fractional ownership.  On the high-end NetJets sells shares starting at roughly $400K for a 6% or 50 hours annual flying time for a seven seater aircraft.

The article also noted that Gulfstream sold 89 new jets in 2005 to service this private jet marketplace, and is expecting to sell 111 in 2006, a 24% increase.
