Well I'm confused. I received my paper statement yesterday, although it was dated April 01. Not real problem, but it means I didn't receive 4 upgrade certs (the difference between 28,000 and 41,000 miles) and that my statement is already 4 weeks out of date even though I just received it.
Of more concern is the on-line version still shows the March 10 statement, which likewise has the last detail on February 20.
