I did my $150k cycle back in Jan-Feb (started 1/31, with last deposit on 2/29 for $150k). How long do these offers usually look back if you sign up after churning for awhile?

For example, if I were to sign up for the AA miles now, would it catch the $100k that I put through back in February? I don't have the cash free right now to churn it through again unfortunately.
