FrequentPR – One crucial point never mentioned is that PAL configures Y class nine-across 3-3-3 for an aircraft designed by Airbus for eight-across 2-4-2 seating.
In fact the vast majority of A330 operators still maintain the more spacious 2-4-2 configuration.
The reduction is seating capacity you mention suggests that PAL is reverting to a 2-4-2 layout.
Checking PAL’s seating plan it appears it operates its A330 in either a 363 or 414 seat versions which must be as dense as that of low-cost carrier Air Asia X.
(Note: Although PAL’s website refers to a 363-seat version the link does not work).
