Supposedly, E represents BF reward seats, and for some reason, some flighs have been showing E inventory on ITN for the past couple of months, with no apparent pattern in which flights show E and which don't. The only pattern is that of those that show E, most are E0

E are definitely domestic FC reward seats, not sure about BF. And there is definitely no apparent pattern to E inventory showing up on ITN -- of the 4 daily EWR-MSY flights, 2 used to show E, 2 didn't. Now none do.
