How to Book a Flight With Points or Miles

If you've been collecting airline miles or flexible travel points, booking with them works differently from paying cash — and getting good value takes a bit more attention.

Where your points actually book

Airline-specific miles (e.g., a frequent flyer program) typically only book flights on that airline and its partners. Flexible bank/credit card points (transferable travel currencies) can often be redeemed two ways: directly through the card's own travel portal at a fixed cent-per-point value, or transferred to an airline partner and booked as a traditional award ticket — the second option usually delivers more value, but takes more research.

How to find award availability

1. Search the airline's own site for "award" or "miles" fares — not every seat on every flight is bookable with points, even if cash seats are available.
2. Compare the point cost against the cash price to calculate your redemption value (cash price ÷ points required = cents per point). Under 1 cent per point is generally poor value; 1.5–2 cents or more is strong.
3. Check whether taxes and carrier fees apply on top of the points — some award tickets, especially international ones, carry substantial cash surcharges even when "free."

Common mistakes

• Redeeming for low-value domestic economy tickets when the cash fare is already cheap — you often get better value saving points for expensive or international routes.
• Not checking partner airlines. Many programs let you book partner-airline flights, sometimes with better availability or lower point costs than the home airline's own flights.
• Letting points expire. Most programs void points after 12–24 months of inactivity — a small purchase or activity can often reset the clock.

When to call for help instead of booking online

Award searches involving partner airlines, multi-city award routings, or combining points with a cash co-pay are often easier over the phone than through a self-serve site, since award inventory can be inconsistent and hard to search well online. If your points search isn't turning up anything usable, a booking agent may be able to find availability you're not seeing yourself.
