<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Therefore, some IMPARTIAL and NON-biased factor should be considered, such as time of checkin. To discriminate against people, based on the fare paid, should be illegal. It's like the airline is saying, "you're not a member of our club, so you'll go last"... it's not much different than if an airline said, "your skin color isn't the one we let on first"... Fare paid is simply an arbitrary and irrelevant factor.</font>
You're kidding, right?
How is it discrimination? You and everyone else had an equal opportunity to pay for an F ticket for that flight.
Upon what possible grounds can you suggest that this should be illegal?
As others have pointed out, you receive a package of amenities when you purchase an F class ticket. Among these is the right to check in later than Y class passengers. To penalize F passengers during irregular operations because they checked in pursuant to their check-in requirements, which are significantly shorter than those for Y class passengers (which your system would require) makes no sense whatsoever.
