Got on a UA flight and the entertainment system onboard wasnt working the entire time so the minute I land, there is an apology email there with 3 options. $100 off voucher for domestic travel on UA metal. 10% off for UA metal on international flights and there is an option for 7000 miles. I fly International 1-2 times a year and mostly to Japan. Domestic is so so. Just enough to usually get me my 50K miles. question is.. WWUD? grab the miles? take the discount? oh. none of my travel is business. its always just for fun out of my own pocket.
