I think you do not need 24 hour flights for that. Some flight numbers are used multiple times throughout the day. If one gets delayed too much, then two planes can be in the sky at the same time with the same flight number.

It’s gotta be a big YMMV thing. I wonder if US airlines might do that domestically only but not for international.

Air Canada will renumber a daily flight if the delay goes past midnight (to avoid having two departures with the same number on the same day). I doubt it’s just a courtesy, but an incompatibility with their (or enough airports’ systems).
