I second normathej. Recently flew JFK>BRU>TLV and back. The BRU>TLV route had a very budget airline type feel. (And I was officially in "Business Class"). However, I think that is standard for short haul European airlines, so I am not sure Lufthansa would be any better. I did find Brussels airport easy to maneuver, which is a plus for a seminary girl. Also, given the proximity to Antwerp, both legs will have a very noticeable frum presence.
The JFK>BRU leg was great, but I was in Business Class.
