Wait.
What?
I don't know why, but it's true. There's a time line built into the delivery of passenger where as you must finish before the deadline. The least I've come across is two hours. Maybe it's the programming, maybe it's the server, maybe it's my dial up connection or maybe it's just because I'm to expedient. But I don't get passenger messages until I've either just arrived at the destination and or in the process of docking. Though I'll read them before they get off, I've learned not to acknowledge them. It has reprecussion by degrading their over all rating of you. Should you acknowledge them, and don't fulfill their request, you get unhappy passenger.
So, I've learned to put those laa ti dahs economy passenger in bussiness, and those laa ti dahs bussiness in first. And just don't bother reading them. At trips end, after you get paid, they disappear from the comm. My economy is only for the mass of refugee's that need transportation to and or from mostly planets. I've made millions and millions hauling them from planet to planet and they never complain. 85% of my dockings are planetary. I've got it down to a science high or low gravity can be accomplished in less than two minutes top.
HINT: Though it won't always be facing directly at you, it will be mostly at a slight angle. But if you want to fall out of super facing those big almost round stations. As you approach them in super, take a few seconds and anticipate a course that will bring you in from the planet side. Thus sometimes basically making a loop of sorts. Except for planetary or ports, I can drop out almost directly in front of the portal every time. There's a image somewhere for free showing the layout of docks on a planetary landing, once learned, makes it faster to dock on planets. Those dammm ports have a system, but as of yet because I do so many planetary, I haven't figured them out, yet.
