I'm just finishing one trip on an Amex Platinum Companion Certificate and have another coming up on which I'm hoping to use another (in an effort to burn the Certificates still left/extended from COVID). The only days I could find for CMH-ATL-DAB and back in May were 5/3-5/19 and, admittedly, the next one is relatively short notice (having a roof installed on a house sometime in June), but is anyone else noticing extreme difficulty in finding days where certificate-eligible fares are available? It seems like every day pairing I've searched for both trips gets met with "Oops! We're sorry...".

I'm assuming it's some combination of "everybody wants to travel" emptying out the fare buckets mixed in with a dose of "the airlines are trying to get every penny they lost during COVID back"?
