Narrative:

While taxiing for takeoff on runway 23 on taxiway H, we were issued clearance to taxi on to hold on runway 23. After acknowledging the clearance, we continued across the hold short line at taxiway Q and on to the runway for the full length. The controller then told us that we were not given clearance for the use of taxiway 1 and that he would have to file paperwork on us. We were then cleared for takeoff and took off uneventfully. We later asked for the supervisor's phone number and called him in-flight. The supervisor told us that they didn't want us to use taxiway Q without asking, but it was a local issue and no violation occurred or would be reported. He also said that it has been a continuing problem for them. This could be avoided in the future with a bit clrer clearance from the controllers and maybe a sign at taxiway Q.
