Dot requires the carrier to follow its own boarding printout rules, and must provide these written rules (as well as compensation) to any idb . Each carrier has different rules
Since we are in the AS forum

[When a volunteer is not found, we will deny boarding to the last customer(s) who checked in on time

American will usually deny boarding based upon check-in time, but we may also consider factors such as severe hardships, fare paid, and status within the AAdvantageŽ program.
Which means for alaska, always check in early (or as late as possible if you want a chance at idb)
Someone can add the policies for other carriers (united is similar to aa, but they will put disabled/unaccompanied miners as last to be denied)
