Rules for frequent fliers are changing
-Try to keep elite frequent flier status on your airline of choice. This can be an entire art in itself, as only miles flown count toward elite status.

-Even if they don't count toward elite status, more miles more benefits. Use credit cards that earn miles on your preferred airline; stay at hotels and book rental cars that earn miles on your airline of choice.

-And yes, try to hoard your miles on a single airline. Make it one that goes the places you fly most often and that has a strong network of partners that serve destinations you'd like to visit.

-Seats to European cruise ports book quickly in summer. Try booking a free ticket to another city that's easily accessible by train or a discount airline. And run the match on those cruise lines' air-included deals, which can save serious dollars in high season.

-Want to use the miles to upgrade? Consider the cost of miles, co-pays and the initial cost of your ticket before you act. It may end up costing more to upgrade a cheap economy ticket than it would to buy a higher-priced ticket that allows upgrades with miles only.

-Most airline mileage programs will let you buy additional miles for a fee; some will let you transfer miles from one account to another. Check the math carefully before you press the "go" button.
