extrange config seats

Hi, i have a question. My TU-204-120 goes from my HUB (Argentina) to an aiport in Brazil (GRU) with the seat configuration 122-20-10, but in the invert flight (GRU-AEP)  the configuration of the seats is 13-20-10. Why?? How can i change it? thanks

Hi, maybe the rwy in AEP is too short for landing with the MPL.

It is a weight restriction. Your aircraft needs 2500 meters to land at max weight in, but the runway in AEP is only 2100 meters long. This means you have to take an 80% weight penalty (100 economy seats are blocked off). In the future you can check an aircraft performance on a route by clicking “Goto performance check tool” on the manufacturers aircraft information screen.
