Shop online. It takes a lot of frequent-flier miles to pay for the average boarding pass, but there are ways to accumulate them more quickly. Evreward.com lists online stores, such as Overstock.com and Netflix.com, that “go the extra mile” and offer bonus miles when you buy from them.
Choose a partner. Most major airlines are part of international alliances, and many allow frequent-flier bookings with other alliance members. When choosing a frequent-flier program, “consider where you want to fly” and which alliances have the best rates for traveling there.
Go for the long haul. Carefully pick where you want to fly. It’s best not to waste your miles on “domestic coach flights.” Instead, be patient. You might just be able to save enough for an international first class or business class ticket.
