It is still offered, but the new name is/will be the United Mileage Plus Club Card. Whether or not any of the benefits will change I do not know.
The website shows the Personal and Business Version Details will be "coming soon". Since my girlfriend fills up often with her job, I have her a card in her name so we can get 2 miles/dollar for gas.
We also eat out several times a week so for us it works out well.
If the new benefits change drastically, I will be looking for a new card.
