These differences mentioned is important for maintenance providers too, at least if company is having more than one customer to take care. Some operators let you in to their own systems, some not -> need to rely airport information system for times/types etc etc.
We have currently customer flying randomly A32x CEO and NEO. This need to be known before arrival just in case we need to do something, not all guys trained/approved CEO vs NEO. Same with 737 CL/NG.
