"Last-minute trips are actually pretty common," said Alex Miller, Upgraded Points founder. "Business obligations, family emergencies, or even that urge for a sudden weekend getaway – there are many reasons you might need to book a trip in a hurry. But unfortunately, most airlines charge a premium for not planning well in advance, so it can really cost you if you're not looking in the right places."
