Upgraded Points: United has announced changes to its MileagePlus program. As of November 1, many business class and first class redemptions will see the mileage requirements increase. Fortunately, most routes from the US weren't hit too hard.
A few redemptions that don't touch the US were increased drastically, though. Probably the most popular route that comes to mind is from Southeast Asia to Australia as it increased from 40,000 to 65,000 United miles for a one-way first class ticket.
