Not sure where you got that idea but you’re wrong. You may have been screwed on pay so I recommend calling contract compliance.

“Flying must touch a DFP. The JCBA requires OG to fly, “on, into or out of a DFP.” While this is not contractually required for PR, the Company’s current process requires PR to also touch a DFP (i.e., it cannot be contained entirely within reserve days and offered to a pilot prior to the time they would normally come on duty). If you wish to be called on your reserve available days for OG/PR trips that extend into your DFP, you must list yourself on those reserve available days when you wish to be called.
• All flying is over guarantee. Ex: If a reserve pilot picks up a 4-day trip that begins on a DFP and flies into three reserve available days, the entire trip will be paid over guarantee.”
