It does say "to cancel online, go to easy check-in online at united.com", but when I do that, I see no options for cancellation/offload.
I pulled up an older boarding pass that I'd deleted - on that the number is: 1.800.589.5582 (option 4) to remove your name from the checked in list. It was for October last year. Maybe that'll work for you. G'Luck.
