Forgive me if this is a basic question - I'm new at this. I'm trying to book US domestic flights for my family of 5 the using my Chase UR points. The cheapest option through the UR portal comes to a total of 114k points, and the partner airlines are at least 25k per person. Booking through Allegiant costs $882 (including luggage), but I don't want to use cash. What is the smartest option here? Should I just take cash back from the Ultimate Rewards to pay for the Allegiant flights?
