Kindly read my suggestions more carefully...I already suggested the B 737-700 with winglets...here is the quote :Boeing 737-300 has a major fuselage modification coming up in 2009, which is costing so high that’s its worth buying new planes, for that 737-700 with winglets is already under study its competitor is A-320 is also being studied side by side with 737.
.........................................The Boeing 737-700 with winglets (to conserve fuel) is the ideal replacement aircraft for the Boeing 737-300 as it has a similar passenger and cargo carrying capability but it can fly further. The additional range that it offers would enable PIA to fly on medium haul low-density routes nonstop, which are beyond the reach of the Boeing 737-300.
These new potential routes are to Damascus, Beirut, Amman and Istanbul nonstop from PIA’s Karachi hub. In addition, the operating characteristics of the Boeing 737-700 with winglets are very advanced and superior to its nearest competitor i.e. the Airbus A 319 as it burns 4% less fuel and flies further due to the winglets.
PIA’s current Boeing 737 fleet numbers 6 aircraft but I feel that it would be worth it if a replacement order for not 6 but 7 Boeing 737-700’s with winglets is placed so that frequencies can be increased on key Gulf routes from Pakistan.
A B 739 cannot fly nonstop from PAK to EU/UK/PEK/SIN/KUL...so whats the purpose of ordering such an aircraft as an effective A 310 replacement. Whomever suggested this should have their head examined as the B 739s too carry less cargo than the A 310 and the seating capacity isnt as luxurious as what can be ordered on the A 310s on medium-long haul flights.A-310 being on lease will go back and will be replaced by 737-900
A B 739 / A 321 is at the very most an OK replacement for domestic + Middle East flights only that have medium density demand...but surely it isnt a replacement aircraft option even to be considered for EU/UK/Far East operations.
it better not be as that would mean them being 24 years old by 2012 and even more inefficient aircraft 2 operate in that future era.Boeing 747-300’s as per plan will retire in 2010, but can be extended up to 2012
I think you have made a mistake here...8 B 747s to be replaced by 8 B 777s and not 20 B 777s...PIA has 12 A 310s so 12 + 8 = 20...PIA is not replacing its A 310s with B 777s so you have made a typo error here. PIA will most likely replace the A 310 as I have suggested with the Boeing 787-800.747’s a total 6+2 will be replaced by Boeing 777 (ER’s and LR’s) mixed fleet will come making a total of 20 B-777.
