Throughout this thread I have maintained that ATC will always help but would look very poorly upon anybody who abused the system.
I ask you to imagine that a company had an aircraft that didn't have particularly good payload/range characteristics but wanted to operate it into a major airport which regularly experienced significant inbound holding. If that aircraft was not able to accept the delay how woud you feel about it being allowed to jump the queue (as a matter of right) so that it could carry a higher payload or didn't have to divert? Purely hypothetically, you understand.
Would that be an abuse of the system?
