I fly Royal Brunei a bit and they have some amazing meals in economy, hats off to their catering crew. I do a hell of a lot of Qantas flying and some of the domestic Econ meals are down right appalling, Neil Perry has to be the worst "chef" on the planet. Some of Qantas biz meals can be OK on a good day but down par compared to other major airlines. Qatar biz meals amazing and Econ meals reasonable. I was impressed with LOT a few years ago on domestic Econ. The worst by a country mile are JetStar and Virgin Econ purchase meals, stale and over priced. Singapore Econ have always been great
