Falcon, take note of the mission terminals and how far they send u for missions.
As omni, u can go to neutral cities and get missions from their terminals. Clan can do the same too. As u level up, u'll need to go further and further away to get mission that send u back to omni territory. eg. U can try going to MORT, etc. U can even find mission terminals in places like SAV, Avalon, etc. Most people just don't make use of them or don't even know they exist.
At level 1 to 50, I can easily get a mission from any Omni city that sends me to another omni city with save terminals nearby.
At level 100+, I can use the grid to go to newlands or borealis to get missions in 20k, or broken shores (city of home) with save terminals just outside the the mission entrace (or a short run away).
U'll just need to take note of the coordinates of such places.
It's not hard, people just need to break out of their routine of doing the same thing over and over again and try new stuff, explore new place and OBSERVE how the system works.
