Lufthansa, or Luftwaffe as I call them due to the... military kindness they often display.
No food and no water. Most recent data point: April 2023, Standard Economy (not Basic Economy). International, 4.5 hours flight (Germany to Tenerife) (and back). The flight had a LH code, although operated by Eurowings which according to Wikipedia is a wholly owned subsidiary of LH (https://en.wikipedia.org/wiki/Eurowings).
Not only that but at the Beijing airport there were no water refill stations and the bottle of water I bought at the airport POST-security was confiscated upon boarding. Fortunately I was boarding an airline with free water, though.
And public restrooms seem to be paywalled everywhere in continental Europe too -- not sure about the airlines, since I usually fly US carriers, but every restaurant or shopping mall I visited in Italy, Germany, and the Netherlands required a euro or so to enter the toilet. I've never seen a pay toilet anywhere in the US.
