25,000 Bonus United Mileage Plus Miles

This year, frequent flyer programs are celebrating their 25th anniversary. American Airlines was the first to introduce the AAdvantage program, and United was right behind with Mileage Plus. I mentioned last month a number of promotions that American was running to celebrate. Now, it is United's turn.

You can earn 25,000 bonus miles using Mileage Plus Dining by Rewards Network (formerly iDine). Spend $125 per month at qualifying restaurants, including tax and tip, every month from July through December, and you will receive 25,000 bonus miles -- enough for one round-trip domestic ticket! You must register first.

I hope that American offers a competing deal.
