Management are giving some spiel about aircraft availability
Well, they say they have been so successful that because of the great success they will not start early, but late - as they now intend to use A320s instead of A319s and only crappy A320s were available on the market, the launch had to be postponed until a later date when more bling bling examples are available.
Something along these lines... At least they don't lack creativity coming up with funny stories.
