Thank goodness for United Airlines, they’ve solved the problem of what to do with grounded, stranded passengers. You know, the problem that Congress has been having hearings about? The solution: a 20% off coupon, a $10 airport meal voucher and a note of apology! The Denver Post says that United will consider anyone with a taxi-out delay of more than 3 hours or a taxi-in delay of more than 90 minutes eligible for the goodies.
