Thanks for the link, rittenhousesq. I just spent a good half hour perusing the discussion! I'm a vegetarian, but my flight info says no special meals are offered. It looks like there are quite a few meat dishes offered. Maybe I'll just pack ample snacks to get me through. Or maybe it's worth a try to call and request it verbally...
Having seen the map and receiving all this helpful advice, I feel much more relaxed! And even a little bit excited. Thanks again, folks. I will probably be posting up a storm once I start flying regularly!
