April 5-19 on Swiss for only $663 and Lufthansa is only $687!
This is a great deal in general for Pesach but if you live OOT this is a smokin' deal because there are such cheap flights from so many cities to Chicago and lots of seats on American into ORD to use Avios. I used Avios for our outbound connection and bought a cheap return ticket to Denver and saved about $400 pp from if I'd bought a ticket from Denver. Plus you'll obviously earn Star Alliance miles.
