Fixed it for you. 😁

And yes, basically they can legally substitute a turn but the exception is pretty narrow. Looks like Drum did not have a turn though if it was one leg to a 30-hour layover. Guess they just treated it like tag-on flying at the end of a regular line holder rotation. Not permitted by the PWA but still dangled out there. The tag-on used to result in IA pay for the tag-on portion. Heard an ugly rumor the Company was starting to pay only the additional time, no premium because they felt the pilot "knowingly and voluntarily" waived his/her/other rights under the PWA and therefore was not entitled to the customary IA pay. As you said, gotta know your PWA well enough to know that something just doesn't seem right.
