Dunno if I agree with this point. Do you think they would sell out -- any more than the current E+ does (which would have to be part of your posit)? I've always wondered, from the first introduction of E+, just how many of these they actually (up)sell, vs. how many are "comped" to non-elites at the convenience of UA (or, on some flights, how many are filled by people I see simply moving up). ...But maybe they would sell more of a premium economy.
