at first i was surprised that my flight would be a 52 dollar upgrade.
...and then read it more carefully and was even more surprised it was for my flight... to austin? funny because i don't have any trips booked to austin. went on to ua.com to do a sanity check ("i feel like i'm taking crazy pills here") and maybe i had booked some wild routing that connected through AUS but nope... nothing through AUS. clicked on the upgrade link and it took me to a $171 upgrade for my flight to BOS (which is a real itinerary of mine).
