I need to get this straight.
Are you saying you were told you didn't get your meal choice because you're NOT Platinum ?
Mrs GPH prefers the A seating, mainly so she isn't disturbed for the entire flight.
We find that the other 300 odd days of the year are plenty to have a quiet chat to each other (lol)
My brief association with QF F, was excellent, cleanliness certainly NOT an issue. We didn't have a full cabin all of the way through to LHR though.
You will miss out on meals if you don't order them up front. Mrs GPH discovered that very early on in the peace !
