[QUOTE=b-kpf;20053313]333s and 773s are the old regional business and economy seats. The new regional business class is not in service yet (I believe the first 773 is currently still under retrofit at XMN). However, CX506 and CX 502 does operate a guaranteed 77W or 747 with the new Cirrus J or herringbone J respectively on certain days of the week (subject to last minute swaps though). The new economy and premium economy product (not sold, usually upon request by MPO elites) might also be offered if you run into a new/retrofitted 77W or 747. 747s and certain 77Ws also offer first class. Check the schedule below.
