I have done CO's EWR-DEL-EWR in Biz a few times and I can't imagine the CO EWR-DEL-EWR coach beting any better than the former. The Biz service was good, but nothing to write home about. The cabin crew had no idea what they were serving. "woud you like a roll or "that?" pointing to a sorry loOking reheated paratha." The Biz service was more elaborate and had better wine but the food on AI in economy was better than the CO food in Biz. ANd that was on BKK-DEL, not on a premium route.
