I haven't traveled outside the US very much but when I was in China, I took a 2 hour domestic flight on Shenzhen Airlines and they served hot meals both ways for free with 2 or 3 choices of meal. I was impressed, I've never received that kind of service except on long international flights.
This was the hot teriyaki chicken, rice, and vegetables with a box containing a roll, banana, pickled vegetables, and candy.
