Yes, you can start at a jet way. When you're selecting your airport, you are on the FSX free flight screen, and there is a drop down menu that says 'CURRENT LOCATION' you click change and select your airport etc. etc. Once you have selected your airport, stay on that screen, towards the bottom middle you will see another drop down menu that says 'Choose runway/starting position:' normally it will say 'Active Runway' click on the drop down menu and a list of runway/gates/parking area/helipads/fuel boxes etc. will show up. Click on one that says for example: GATE B 9 -- GATE MEDIUM. This will make your aircraft appear at a jet way before a flight. To end your flight at a jet way, you will have to contact ground at the airport. Pull off onto a taxiway, open up the ATC windows (a short cut is to press the tilde '~' button located left of the 1 on the top number row of your keypad) After you open the ATC window, You should see an option that says something similar to Contact ground on 121.9. click that option and most of the time the first option is request taxi to gates. If it isn't you will probably see a lot 'request taxi for' options, on the bottom the 9th option says something similar to 'taxi to parking/fueling. After you click that you should see the top option of 'request taxi to gates' as I mentioned earlier. After you click that, you will hear some ATC communications and you will be assigned a gate. You can turn on progressive taxi and follow that to be taken to your gate.  :)
