Well, if you make the simplifying assumption that passenger-variable cost = 0, then
revenue per seat mile = (average fare / route length) * load factor
but for breakeven, cost per seat mile = revenue per seat mile
therefore
breakeven load factor = CASM / (average fare / route length)
You can probably find enough data either in airline annual reports or in US DOT filings (if it's US airlines you're interested in) to calculate breakeven load factor by airline on an aggregate (total-network) basis. I believe that US stats may include average-fare data by route. If that's the case, and if you generalise an airline's network CASM to a specific route (admittedly a very dangerous assumption) you might get a
very rough idea of the BE LF for that route.
