Great to be reporting a minor suggestion now I've got GSX Pro working, it's great.
The answers to the prompt "do you want to deboard crew" are a little strange for an English native speaker.
-Nobody
-Crew
-Pilots
-Both
Suggest "Crew" is changed to "Cabin Crew", as crew is inclusive of pilots and cabin crew.
Suggest "Both" is changed to "All", both sounds like 2 people (ie, both pilots). As the question doesn't specify the two options, the answer both doesn't really fit (it would if the prompt was "do you want to deboard pilots or cabin crew?").
Very very minor I know, and this is a suggestion not a complaint.
