I was wrong thinking the current CM
's 738s struggle technically in some long operations, such as PTY
1x daily and PTY
2x daily. These segments are not far from the maximum comfortable bound established for the 738 fully loaded. Such range is roughly 3000 nm.
I would assume great loads for these tracks, because the 738 is the biggest plane involved on their entire fleet.
It is not necessary to deploy a better airplane in range as the 73G in such routes, taking into account its overall capacity in both passengers and cargo is less than the amount for the 738.
More seats mean payload restrictions are not an issue yet for CM
's "long-hauls" with 738, making these routes even more profitable for them.
However, the comfortableness for passengers should be reduced due to the areas that are being seemingly sacrificed when such reconfiguration come into force.
