Mixed class booking - route specific?
 

For some reason, JetBlue.com seems to offer mixed Mint/economy bookings on some routes (for example, SFO-JFK-BTV) but not on others (SFO-FLL-SJU). No luck with the call center, either - they claim it's a "system problem", though that doesn't square with the Burlington example above. I'm told to book separate tickets.

Has anyone else found a workaround, like using a travel agent who can book the legs separately on one PNR?

There was another thread about this fairly recently, let me dig it up.

EDIT: Found the thread but it isn't much help. Sorry.

You can't do a mixed class via multi-city. You can only do a mixed class booking if a through-fare between your origin and destination is loaded in the system. There is no way around it that I know of.

The only way around it is to get someone at JetBlue to file a new fare allowing the mixed cabin option. I had success a couple years ago getting SFO-IAD added when I asked about it.

This particular routing (SFO-FLL-SJU) is now pricing properly.
