And AY must think they get the most out of their FF program with the current levels. The people complaining here think AY+ doesn't amuse them well enough.

I agree that it's not that difficult to reach Plat. OTOH, the amount of Plats doesn't seem to be a problem. The upgrade space issue is slightly different from the amount of elites, because many flights start with no upgrade availability at all (so the lack of upgrade space is not because of hoardes of elites using their vouchers) and it seems that elites can still clear their upgrades pretty well through the waitlist.

Regarding upgrades, I think the following changes would help:

• have a few upgrades available for every flight, even for Basics
• have some more published upgrades available only for higher tiers (e.g. 1 for Lumo, 1 for Plat, 1 for Gold, and more if the flight is expected to have only a small amount of paid J customers)
• do not leave J seats empty if there are waitlisted upgrades
