I’ve been traveling a bit, so forgive me if others have beaten me to writing about this:
There is now a United Explorer credit card offer where you get 50,000 miles after first purchase; 5,000 miles for adding an authorized user to the card; plus a $50 statement credit. This is the first offer I’ve seen with the 50k miles PLUS the statement credit.
$95 annual fee is waived the first year. You must have some miles in your Mileage Plus account to be able to see this offer. Also, if you’ve had any United credit cards in the past, you won’t get the bonus.
