We haven't changed anything, the scoring rules are always the same, we only fixed an issue with the catering rules, not the handlers.
As a general rule, you should never rely on airline codes in a parking to control the scoring because, after SU12, GSX doesn't read the airport .BGL anymore so, airline codes won't be read from the scenery anymore, even if they ARE present in the scenery, because they are not supplied by the Navdata API.
It's much better if you set the proper operators explicitly, so you won't be dependent on airline codes that might be missing, changing or even be wrong.
