I agree with KHI747
that the PIA acronym should be dropped and with Yyz717
regarding attracting more non-Pakistani customers, but since the airline is financially constrained its bets that they stick with either the present look, upgrade it a bit by painting the engines Green too, adjust the size of the "Pakistan" title as some 742 and the 743 are wearing larger versions with a thicker font while the rest of the fleet has still got the older thinner font style as can be seen in the photos of the A310 and the 747 in the posts above, also the Urdu logo on 747s should be brought down to the below window level like on the other aircraft and again the size adjusted accordingly.
my mail was for you to write a letter to Ahmed Saeed requesting him to have all of the planes in PK's fleet painted in their full livery as the two distinct versions being worn at present really look bad, being a businessman he should know that a good image counts, so if you can then please write to him, not email, but write or type a letter to send they never respond to emails, heres teh link to my post about the floral tail on silver, Air Orange
was kind enough to do it but with his own floral version as he could not download PIA's one on the Adobe Illustrator http://airliners.net/discussions/general_aviation/read.main/561596/4/
