Please note, the B737NG was mentioned because the worst kept secret in the company.
This was that the airline has been looking at the costs of operating our existing fleet and the B737NG.
This includes l believe cost to fly and maintain current fleet until the B787 is available in numbers, which covers different heavy "C" checks that may be required.
I also understand that the cost of maintaining each aircraft on a year on year basis, given by the manufacturers and what has been learned from operators differs some what.
I only hope that the board is looking how the A320NEO & A321NEO compare to current A320 & A321 and the 737NG.
The reason l say this because it looks like the 737NG is going to be behind the curve with regards to the A320NEO & A321NEO.
Should know more by the end of next month.
