If you are enroute to several airfields with a landing each time and you need to state your intentions do you than just mention "enroute from Oxford to Gloster" and leave out the airfield that will follow on the next leg after your first stop?
So for Gloster it is not necessary to know where you will head off to next.
Eventuelly you are wise to book in by telephone in all airfields anyway with an approx ETA right?
