It appears that the annual cap on the number of AA miles one can buy has been raised from 40,000 to 60,000 for the new year. I haven't checked UA for a long time, but my memory was its cap is 60,000, and I don't know about DL's (or US's, ugh), but it is possible this cap change for AA is a competitive response. https://buy.points.com/PointsPartne...nguage=EN&product=BUY&CAMPAIGNCODE=AAMktPgDom This is not a huge change in that historically AA and points.com ran "special offers" during the year raising the cap during the offer from 40K to 60K anyway. Also be aware that now it is January and there do not appear to be any special monthly bonus miles thrown in -- as there were as recently as December, yesterday -- for miles one buys right now. EDIT: AA now HAS added a bonus for miles purchased in January, though it is not as lucrative as the bonus in effect before New Year's Day. Nonetheless, for what it is worth, it appears the cap has changed.
