That's good to know, but I'm still curious about how accurate EF's data is. The biz cabin is reasonable free (9 of 30 taken) and has C, D, J and O available (now, I class is zero, but it was also zero on the other three segments I booked, before I booked my J upgrades).
Any further data to be had out there? Thanks again!
