I found an interesting fare in Africa (in the GBP1.83/TP range at the maximum) but though EF has the fare filed and ITA can construct a journey around it, none of the OTAs seem to want to offer it - even as a simple point to point, rather than the complicated TP-maximising route ITA allows
No joy with bookwithmatrix either.
Any hints on how to see if the fare really exists for booking? Don't really want to put it here if it's just a mirage. Thanks!
