Sorry this happened to you (and so many others). It's really high time that UA fixed this. I find it really irritating that even though other airlines can password-protect reservations (see the blog post referenced in
this post), somehow UA can't or won't implement that functionality.
Maybe put a 24hr Delay on CA cancels before redepositing into the bucket. Gives us a chance to call and rebook - and hopefully change the confirmations number around, meh.
