The alliance between country's two biggest private carriers Jet Airways and Kingfisher Airlines will take six months to be fully operational, according to Kingfisher Chairman Vijay Mallya.

Already the two carriers were cooperating "very closely in many ways" but it was not as simple as it sounded to operationalise the agreement, signed by them last October, Mallya told PTI.

"One project is taken at a time. If you decide that frequencies on a particular route operated by either Kingfisher or Jet are going to be changed, it is not as simple as making one phone call to the planning department and saying stop the flight," he said.

Asked if the alliance could take off fully in the next three to six months, he said: "Absolutely, hundred per cent." For the deal to be smoothly implemented, Mallya's Airbus based fleet will have to be synergised with the largely Boeing based fleet of Jet.

When the hand-holding process by the two would be completed, they will command a market share of about 58 per cent (based on calendar 2008 figures).

Let see hoe far this new alliance will go, looking at the way how Deccan has performed I expect Jet also to perform in the same ways. Too early to predict any thing now
