I don't think Shaheen would be willing to expand their fleet because if we compare airblue and shaheen, it is clear that airblue is taking a huge leap to go as far as Manchester with a plane which can't go that distance without a technical stop. Surely airblue could be thinking of A333, A343 etc. but this coming to reality seems to be very far. Maybe Airblue will but I have no reports on airblue funds and income!
But looking at our passengers amount from and abroad of Pakistan, there is no doubt we need planes like A330.
(I know people will be saying to me, PIA should improve their service first then induct planes)
