Hi there - I saw it in one video but I'm not having trouble finding the option.

I would like to change from two class seating setup (First class and Economy) to one class configuration. 

 

There should be an option somewhere in the FMC but I can't seem to find it. Anyone know where is it exactly?

 

Thanks in advance.

You'll find it in the PMDG SET-UP menu. Under Equipment Options/Cabin Layout IIRC.

Thank you so much!
