Hello all,

I'm due to take my first F flight on Cathay soon (NYE "promo" fare).

I read that F has dining on demand, and I wanted to find out what the rules are so I don't unnecessarily annoy the FAs. Should I tell them at the start of the flight if I intend to have meals at a different time of the flight than is usually scheduled? Are there items that cannot be had off-schedule? Are there times to avoid in order to minimise hassle (obviously not while taking off/landing, but should I avoid asking for breakfast during dinner service?)

Cheers
