Are you a member of an airline frequent flyer program?

Chances are, you belong to two or more.The main reason people join is to earn status and qualify for elite perks, like complimentary upgrades.

Now, airlines are turning those status upgrades into an impossible dream, because snagging a seat in the front of the plane has far more to do with how much you spend than your mileage tier.

Flying with status on American, Delta, or United, and think you’re first in line for a free upgrade? Think again.

Airlines are now selling those premium seats within 24 hours of departure to all passengers, with some upgrades going for as low as $36.On long-haul flights, American has a new rule: even if you’re a Mega Million Miler, buying a coach ticket only makes you eligible for an upgrade to Premium Economy.

If you want to sit in Business or First, you have to buy a Premium Economy ticket first. So much for loyalty.
