I got my ticket yesterday. I have enough SkyMiles for a r/t TLV-ATL in Biz at the low rate, but not enough for the middle rate.
I got a low rate ticket flying out (arriving Oct 19) and took a return low rate ticket for sometime in late November. When I finish the trip I will be starting on Monday, I will have enough SkyMiles to change the return ticket to a middle rate one for late October.
