Yesterday, Sunday of Thanksgiving weekend, aka "busiest travel day of the year" 11AM BOS-SAN was oversold by two seats. They immediately offered $700 vouchers each and a seat no the 4:30(ish) flight instead. We needed to get home earlier so passed on the offer, but a solo traveler ran up and grabbed one of the two offers. A family of 3 also offered but didn't want to get split up. Agent said they could all move to the 4:30 flight but could only get 2 vouchers and they refused.

I didn't see anything after that, but we left almost on time (catering didn't show up until 25 minutes before scheduled departure, even though the equipment was there overnight), and made up some time en route until we sat for 10 minutes next to many empty gates waiting for the only gate we seemingly were allowed to go to was available.
