IMHO, things are better mileage bonus wise then they have been since the days when you could churn UAL and AA cards every couple of months.
Chase has been very, very generous to me recently. 100K on Saph Pref, three INK Bolds at 50K each (one with no spend requirement), UAL Explorer at 50K and several more.
The miles are coming in faster than I can use 'em. (Note to self--gotta fly F more!

Use more miles! @:-)).
The glass is not only half full, it is refilling itself.
