How often you fly with MTOW on A320 and/or B737NG

[Jan Vana]

Hi, I wonder how often (in percentage) you fly with MTOW on A320 family and/or B737 NG. I assume that this is mostly only on the routes close to max range or on the standard routes (1,5-2 hours) with a lot of underbelly cargo. Am I close to reality?
