The best - August '97 once in a lifetime BA concorde...British made food & hashgacha, 3 top choices for main course. They oferred a glass of Port after the meal- strange? or just protocol?
The worst - the black "stogel" super-long-shelf-life boxes. appearing on many non-US airlines. I think its some sort of backup or even default, especially
on Asian/Japanese routes. It's entirely non-perishable, u dont get any bread, just crackers...better stop here
Hermolis is nice. CX-NRT economy is a lottery - somtimes Hermolis, sometimes Stogel, u never know. at least the Haagen Dazs is kosher
On trips to Australia and NZ with QF and CX i got AU / NZ local hashgacha. No major complaints there, the Sydney one was nice.
I do always take food. I know someone who got 15,000 miles last month fm LH for forgetting his K meal 6 times in 6 months.
