I seem to recall getting these maybe once a year or so on an old AA card. they are usually kind of weak tea.

once we got one on that offered two Admirals Club passes for $500 in spend or something, and we registered, did the spend, but were never sent the passes.

we called in once over it, got nowhere, so stopped paying much attention to them aftewards.

maybe if its TYP or something they are easier to track / deliver on.
