But, there is no discounted fares even when I tried dummy bookings for March 2024.
It's probably no surprise that it didn't work for August departures, given it expires before then

But it was working for me just now for flights Europe to CPT in March, provided I avoided the blackout dates.
Perhaps departures ex-MIA are not included in this offer. It is best to scrutinise the T&Cs listed on the offer page of the departing country's website. If not there are no doubt a bunch of other discount codes if you search, although expecting these to apply during peak holiday times is usually wishful thinking
