No, 6 seats open PE only
Looking at the seat map I see 9 empty seats and 40 or so blocked seats <-- blocked seats are the ones that can go either way.
Business is chock-block full - 2 empty, 4 blocked (<-- this suggests blocked seats are partially empty).
You need CX to sell around 20 more Y seats before they need to op up people from Y. And for PE to not sell any more of the 6.
