I'd check back in about 76 years.
bad joke. Business only routes like those prioneered by LH
using Privatair seemed to have worked, but I haven't seen anything yet that suggests they worked incrediby well.
Business only airlines like Primaris, MaxJet and EOS seem either to be struggling to get aloft, or stay aloft.
OzJet in Oz was a total joke and was thrown out of the market so fast its undercarriage scarcely made an impression. Its market share was equivalent to a statistical margin of error.
A common issue for business only airlines is that there really aren't too many rich individuals out there able to chose their own carrier contrary to the dictates of corporate travel policies that lock people into whatever the company has negotiated with whichever airline.
And companies are very reluctant to pay for premium fares anyhow these days.
The rich bastards are all in their BBJs, or if its me, the first class suites on an Emirates A345.
I think corporate airlines, that is, a company that fully leases say two or three Global Expresses, is a real chance, but otherwise, being a business only airline is an incredibly quick way to burn money while the big carriers target your offerings with deals on more frequent business or first class deals that will only last as long as it takes the lessors to reposses your jets.
The big money in my humble uneducated opinion will come to carriers that offer a really good premium economy class, semi naked oil wrestling women flight attendants, and a broadband link for the workaholics.
