I'm trying to book a ticket on CO from EWR-TLV-EWR, leaving on (or around) April 12, and returning on (or around) June 22. For some reason, every time I try to get a Z class ticket, it doesn't show up, and instead offers me a C ticket. However, if you put in the exact same dates for LAX-TLV-LAX (via EWR) it DOES give you the Z ticket, and the LAX ticket is cheaper than the EWR ticket!!
Any suggestions?
