Mileage Run Discussion - advice/experience with compensation on MR's

I searched this thread & did not find answers to my question........

Any FT's have experience volunteering to give up their seat and take a flight credit on a MR? Is the compensation always a $300 flight credit? Does the airline agree to re-book all other segments w/o a change fee? What is the best strategy for maximizing chances of being offered a credit? e.g. late check-in?

I recently completed an MR : EWR-DEN-TUS-LAX-EWR on UA. 1st segment was oversold and was asked if I was willing to give up my seat. I was, but in the end they not need it!:( What a pity! :( (It would have paid for the MR!)

Thanks in advance for suggestions!

the best thing that can happen is to get bumped some where early along the line & get routed home & get orc....

While a few years old this thread does talk about "bumps" while on MR's:
