i recently made diamond on BR a few months ago.

i typically buy Z/J/C business tickets straight up. however, now that i have 4 systemwide upgrades, i am considering buying elite and hoping to get an op-up... and even if i dont get an op-up, i figure i could always use my upgrade at checkin.

also, do sites like expertflyer help you select flights that have a higher chance of getting op-uped from elite to C?
