Want to change AA flight booked through Avios but no availability

[shidduch]

I booked a flight using Avios on AA for tomorrow morning from CLE - NYC, but I want to fly later in the day.  However, the problem is that there are no low level award seats available later in the day.

If I "miss" my morning flight, if there is regular space available on a later flight will I be able to use my ticket from the morning to get on a later flight?

Flat-tire rule, though it's YMMV.

"American does have a flat-tire rule for customers who call the airline to advise that they won't make their flights, according to representative Tim Smith. This call must come in no more than two hours after the flight's scheduled departure. But that doesn't guarantee them a spot on the next flight out: Passengers travel on a standby basis only."

I have done it more than once, just told them I didn't make it on time (3 hours late). Didn't need to lie. Put me on the next flight without issue

Thanks, I guess its probably not worth the risk.
