50,000 Mileage Plus miles for United credit card from Chase

I wonder why the credit card companies are complaining about new regulations that they think will destroy their profitability and then go ahead and offer mucho miles as signup bonuses. The latest is Chase, which offers 50,000 United miles for signing up after spending $250 (no annual fee for the first yer). To get this deal, you need to call 800-421-4655 and then:

1. Choose "manage my account"
2. Enter your mileage plus number and zip
3. Say "more options"
4. Say "apply for a United Mileage Plus card"
5. Tell the rep you're applying for the 50K mile offer.
