You won't get paid for a premium trip that gets removed in advance (i.e. before report when no suit-up pay is due.) However the reason it was removed could have ramifications.

If it was awarded in error and later removed, you should look for any other flying that you would have otherwise been eligible for award during the period that the removed trip was on your schedule. As in, if you were awarded a GS in error and it sat on your schedule for 6 hours and was later removed for an error, meanwhile during that 6-hour period other GS went out junior to you that you could have picked up had the error GS NOT been on your schedule, you could be due pay for the missed trips.
