Flying from PEK to XIY and then XIY to HKG. In booking the flights on ITA it shows availability in both First, Business and Coach. When I look on seat guru the equipment (A330) does not show F seats. Is F not a class of service on MU inter-asia flights? Or is it like the US that in 2 class planes one is first and the other is C? I do not want to buy an F ticket only to sit in J. Confused, please help. Thanks!
