^^yeah you won't be sitting in a transport for 30 minutes...more like 5 or 10 MAX (including maneuvers to avoid air patrols, strategically position, etc.) I'm sure spawn points will not be so far apart from each other that it will take longer. I don't know how it works, but just by observation I would imagine flight time will take no more than a few minutes...if the pilot knows what they are doing of course...then the flight may be even shorter...if you know what I mean
