From FT, the United MP Visa is now offering 25000 miles after you spend $250, and is waiving the first year’s annual fee. 25000 Mileage Plus miles are enough for a free round-trip ticket within the USA and Canada. This offer is good for both the personal and business versions of the card.

Edited 10/22/2010: The offer above has expired. To view the current United Mileage Plus promos, see the following links:
