I typically redeem 1400 LY points for Y TLV-EWR tickets. AA was charging around 70K miles for that same ticket until this summer. I'm not 100% sure what they are charging for a similar ticket now. From what I can tell C TLV-JFK would be 135K AA miles.
To compare to hotel nights we may try to use SPGFlights as a gauge, you would be charged 295K SPG points for the C LY flight JFK-TLV. If I then look at
http://www.starwoodhotels.com/prefer...omparison.html to see what I could get for the 295K points, I see that I could get as an example 15 nights at the W in NYC as a Cat 6 or 10 nights at the St. Regis NYC as a Cat 7 or 42 nights at the Sheraton Moriah Tel Aviv as a Cat 3.
