According to our
Aircraft Type Search here is a brief extract regarding the -700's and -800's here in Australia.
Qantas 737-800's all use CFM-56-7B24 engines and have a MTOW of 78390kg
Virgin's 737-800's also use the CFM-56-7B24 but have a MTOW of 79180kg
Virgin's 737-700's have an MTOW of 69000kg. The register shows different powerplants of the same model tho. CFM-56-7B (20/22/24).
According to CASA's figures I'd say that the 700's cruise performance would be crap as all the 737-700's in Australia have fixed landing gear !!!!
