I'll be travelling on a CO award ticket to Israel this April JFK-FRA-TLV-FRA-JFK in business class. (I don't have elite status with any airline.)
JFK-FRA and FRA-JFK legs are on Singapore, FRA-TLV and TLV-FRA are on Lufthansa. I've never flown business and never flown either of those airlines. Any general advice, as well as specific advice about best seats, best lounges in JFK, FRA and TLV, and place to stay overnight in FRA on the way home would be greatly, greatly appreciated!
