Well, it seems like the warm nuts are dwindling. On my last 7 transcon flights in January, EWR to SNA, LAX, and SAN (and the other way), have had no warm nuts. Packaged nuts from SNA, though menu says warm nuts, and all the EWR flights have had nuts in the bowl, but never warmed. Service has been average. The menu says "warm" nuts, but doesn't seem like that matters. Just my recent observations.
