Today I handed out the last one of my Kudos voucher to an outstanding FA in F on the DFW-SFO route today. This voucher was the last one that I had with an expiration date (January 2019). Now I need to work on the pile of others that I've been hoarding. I have been wondering if AA is monitoring my stash and will now send me new ones once the FA's turn them in (past four weeks I've given out the 4). Or am I just being optimistic and idealistic that AA actually is tracking my inventory and will replenish it as the vouchers are being redeemed?

BTW, which Elites get these vouchers? I half recall receiving multiple batches as I progressed from Gold to EXP in recent years. This year, I've not gotten any and I turn Exp in July.
