I'm looking for CLE-MIA on 29th, return the next day, using Avios. Virtually the entire month has 7 Milesaavers available (a few 3's & 5's for good measure), except for the 29-30th.

Availability on KVS shows Y7 on the 29th, and almost everyday the rest of the month. Is there any good way to gauge if an award will pop up? If not looks like I can do PIT-MIA-CLE, but early flight makes it a PIA.
