United Airlines tweaks frequent flyer program to reward credit card spending

United Airlines has tweaked its popular frequent flyer program to reward credit card spending. Instead of awarding one point per dollar spent on flights, cardholders can earn up to 2 points per dollar spent on United Airlines purchases. In addition, cardholders will be able to earn one point per dollar spent on all other purchases. The new program encourages cardholders to use their cards not only for United flights, but also for everyday purchases such as groceries and gas. United Airlines is hoping the program changes will stimulate spending and encourage more customers to use the card.
