Hi,
Just added some J class configuration to my brand new B737-300 -> and selected 5 seats with J (lowest option available)... this got me thinking, how is this possible with 5 seats? aren't the normal B737 configured 3x3 so a 5 seat then is 2x3?
I'm not sure the game is 100% accurate in modelling the configs in this sense... that said, small premium classes on an a/c are sometime accomodated in areas where a fuselage is slightly narrower due to bulkhead fittings etc.
737s are normally 3x3, yes... but J class seats may be wider :)
All the 738's that I have flown in j were 2x2.
The seat calculator is based on a mathematical formula rather than on standard practices in the sim anyway
