hi stephen!
Welcome!
by booking, are you intending to use propilot or fly offline?
for propilot, press "divisions" on the main four buttons of the website and then press "propilot" below. It will request you to log in(unless u already did).
there just press lock flights and search for the plane you want to use and check out the available flights.just click on the flight you want to fly and lock it.
for offline, press "pilots" on the main 4 and then "timetable".
just search for the flight using the available options.
Happy Flying with us;D;D;D
P.S. sorry if it sounds confusing:]
