Ideally for international TATL or TPAC business class seats and upgrades or Hawaii upgrades.

As a practical matter that has become difficult on UA the last few years due to *A blocking and obnoxious inventory controls. And the upgrades will soon be a worse deal due to the heinous co-pays (ditto for AA and CO).

Also would like to have used for coach travel to Cancun and Orlando but found that impossible during peak season on all major carriers.

As a result the only miles I've burned last year were for my infant on SFO-BOS-SFO. Well worth the 25k cost even though she could have travelled on my lap for free, as she slept the whole way. The only thing that pissed me off is that UA would not refund 5k when it launched an award sale.
