Hello Umberto! Thanks for all the awesome work, can’t imagine flying without GSX these days and I recently started getting into GSX profile making so I feel more invested than ever.
Not sure if this is the place for such requests, but - would you consider adding Welcome Airport Services (WAS) in one of the upcoming updates? It’s the largest airport services operator in Poland and has a presence on almost every major Polish airport, including 4 biggest ones (Warsaw-Chopin, Kraków, Gdańsk, Katowice).
