Read what he said carefully, Raven:

"We will launch the budget airline if there is a major dent in our revenue."

How do you define "major"?

The airline loses hundreds of millions of dollars each year already, so I guess there is no hurry in launching a budget carrier.

If we go back 2 years, Al Baker was saying:

"Personally, I am still against the idea of a low-cost carrier."
