Jo, welcome to Flyertalk. Your posting was made in a place where bulletin board administrative issues are recorded.
In order to get members to respond to your question, you will need to offer readers more information. Primarily what airline you are flying. Once you can answer that, then a specific forum appropriate to that airline should be visited (British Airways, Delta, etc.). Also there is a
Religious Travelers Forum you might want to visit and search through. The subject of Kosher meals may be broached there.
