United flight 363 from Newark to Honolulu was supposed to be operated by a Boeing 777 on Saturday. The airline swapped the plane for a Boeing 767-300, and that meant fewer business class seats. The airline needed ten volunteers who were willing to downgrade.
These ten passengers each received $10,000 in travel voucher compensation for volunteering, or $100,000 total for the one flight, and they still got to fly in premium economy seats.
