Thanks for all the responses - still trying to get award inventory out of UA and their partners via all East Coast gateways and of course Chicago. I can get 2 seats to TLV (ORD-EWR-TLV last leg on CO) with some flexibility but absolutely not even one ticket back from TLV to ORD for a period of about 6 weeks, (starting early July all the way thru mid August) not even with GS inventory.
It looks like I will need to book award tickets to Europe someplace and then buy tickets from their to TLV and back. Vienna is a good option and we're also looking at London as the boys have not been to either location.
