Become say Plat with CO but it will cost you dearly the free tkts as it will be EasyPass so a Biz to TLV instead of the Saver 115k will be 300k. Domestic 50k instead of 25k
And ALWAYS will never be the case since if a flight is sold-out no way to get tkts
If you want to know if theres a 100% way for Saver tkts None that I know of, however it may help if like me you have miles stored up on all 3 Major Programs (OW,*A,ST)
