Do others know where the United/Chase offer stands presently? Last year, of course, there was no limit on how much of the double miles for tax payments one could get. Then with the start of this year, there was a new double miles offer, but only on $2500 of payments between 1/1 and 1/31. Now, it seem there is another such offer for payments between 3/1 and 4/1, again a cap on the doubling at $2500. This is my understanding from a Chase rep just now. (The website small print explanation is less than crystal clear, and it is pointless to call the toll-free number, which is an automated response.) I gather there will be a similar, limited opportunity each quarter.

Too bad, it was a great deal in the past.
