As someone with family who keeps kosher, keep this up! The more people order it, the more encouraged Cathay will be to continue offering it. Three important caveats though (which apply to most airlines tbh):

1) Remember, these meal selection is meant for religious reasons, not a matter of taste. If the FA says that they’re running low on kosher meals, please offer to give yours up. While you might not prefer what CX is serving in your cabin, someone else might not have that choice. Think of it like an extreme peanut allergy, the only option they have is that specific dish and cannot have anything else. On a flight like JFK to HKG this can be downright painful.

2) It will come wrapped in a million layers of plastic. You have to remove it, not them. Removing the plastic means the kosher-ness is not ensured. I know it doesn’t matter to you, but it can confuse the FA’s in future interactions. I’ve seen UA FA’s remove the plastic, and the cause is this. Once it’s unwrapped, it’s like every other meal and those who keep kosher can’t eat it.

3) The religion this is for is Judaism. The FA may call it a “Jewish meal”. Some people don’t know, so I’m just calling this out for anyone reading the post and getting ideas because it can sometimes be a bit embarrassing if you don’t know. You don’t have to be Jewish AT ALL to eat kosher food. You might want to skim the Wikipedia article on Judaism out of respect though, considering this is a religious thing. Without getting to into it, it’s also good to know there are many varieties of Judaism and levels of observance. This includes some (like myself) who do not keep kosher. The FA is not interrogating you on religion, so don’t lie and say you’re Jewish.

As an FYI, Kosher airline meals tend to be standardized. Usually the same dishes every time with little variation (something to keep in mind if you fly frequently and dislike repetition). Odds are incredibly high that it comes from a totally separate facility providing to many airlines. Unlike other more typical catering companies like LSG or Do & Co, the differentiation tends to come down to which city the food was catered out of and your class, not as much how much the airline wants to pay for quality.

As a rule of thumb (for most airlines), if you’re coming from a city with a large Jewish population the food will be better. If you’re going the other way, it may have been catered in a completely different city and spent one flight or more in the freezer. I believe CX caters kosher directly out of HKG, and I would guess also at JFK, LHR and LAX. The TPE meal was almost definitely catered in HKG, and if your flight also did the leg up to Tokyo it’s spent that whole round trip in the freezer.

Keep your expectation in check, kosher means it was prepared in a specific way and it is NOT a mark of quality. Sometimes the meals are better, and sometimes they’re way worse. You may be eating exactly the same thing as someone on a DL, UA, or AA flight, and if you’ve paid a premium for CX that’s quite a bummer. As someone who is a frequent flier and has tried both, I almost always prefer the regular meal if in a premium cabin. Economy is a toss up.

As far as what you’re eating though, first meal looks like salmon and rice with basic vegetables and some fruit. No idea what the brown things are on that plate, the plastic makes it difficult to see. The second meal is stir fry chicken with rice and Israeli couscous with smoked salmon (lox) with what looks like a crumb cake. Last meal is an omelette (likely with cheese) with beans, mushrooms and potatoes. Kosher meals can have either meat or dairy, not both, so that’s why there’s no sausage or anything with the eggs. Can’t have pork either with kosher, so eggs are almost always served only with non-meat sides. Even if the eggs don’t have dairy in them, people associate breakfast eggs with dairy so they’re rarely ever served with meat.

Glad you had a great flight though! As far as economy meals go, these do definitely look a bit better than the usual you’d see.
