CO.com glitch
 

Has anyone else noticed that CO.com is refusing to display mixed Y and C itins when part of the itin doesn't use a plane equipped with domestic F?

Typically when I searched BF availability (from DCA) I would get routed through EWR with a note that the DCA EWR segment wasn't F (or C). However I was looking at a flight to BOM and comparing the Y and C fares and when I asked for the C fares I got routed through ORD to EWR to make sure I got an F seat domestically.

This was a problem I've had on .bomb, but never experienced it on CO.com (and, honestly, one of the things that kept me from making C class reservations on .bomb)

Anyone else had this problem recently?
