I am happy to hear that you will at least consider it as a plus in the making. Can we hope that we will have a definitive answer or added services before mid of next year ? (Not oblige to answer but it's just curiosity).
I hope we could do it before that date, but you never know with software. In general, we are raising the level or complexity and detail in the services, the new refueling system will show that...
Furthermore, I would like to know if it's already possible to have luggage carriers on the left side and how does that work ?
We support loading cargo/luggage from the left side since several years: some of the planes included in the default configuration are already doing this (for example, some of the Wilco CRJ/ERJ ), but you can do it to any plane with the GSX airplane configuration editor, by placing a cargo door on the left, and rotate it 180 degrees, being sure the green arrow is pointing "outside".
