Now officially on sale. Prices the same as the A333 (not a given on all airlines...) at $2632 RT from TLV in J ($3692 from JFK)
PE at $1789 from TLV and $1879 from JFK (pretty standard for this route)
As far as the twice daily schedule, it still seems a bit uncertain. For now it's on sale starting Dec 13, but from Jan 17 through Mar 31, the afternoon flight is currently zeroed out on all days besides Monday and Thursday (Thankfully there will be a early Thursday option on DL).
