The article implies he simply used the cards to buy stuff he would buy normally which put him over the threshold dollar amount to earn the bonus miles. If this is true it's equivalent to getting the miles for free since he didn't buy anything out of the ordinary. I'm assuming he paid the cards off in full each month

You're ignoring the opportunity cost of having a card that gives airline rewards instead of, say, an Amazon Visa which wouldn't get him any "free" plane tickets but would instead get him Amazon gift certificates.

Credit card companies will give you free money (a portion of what they charge merchants), and that really has nothing much to do with how to travel cheaply.

If someone said "here's how to get $500 of stuff on amazon for $50" and the trick was to use $450 in amazon rewards earned from normal credit card use, that'd be a dumb article, right?

Yes but you're ignoring that $4000 spend on Amazon Visa might net you a $40 certificate (@1%, I dunno the exact reward) where as $4000 spend on British Airways Chase might net you 75,000 miles (incorporating their bonus) which might represent $1000 worth of airline ticket.

In my experience, assuming you fly, the airline reward cards are the best in terms of the $ value of the reward.

Hmm. How can the airlines possibly give away 25% of what you spend? They are only making 2% of what you spend from merchants for providing the card or something thereabouts.

edit: Maybe some airlines do it by only letting you use reward miles on seats that they wouldn't have been able to sell anyway or something along those lines. But some don't. I know Southwest reward tickets aren't heavily handicapped or anything lame.

1) Signing on bonus. That 75,000 miles extra reward miles is a "one-off" for spending a certain amount at the start of the card. There is a cost of customer acquisition (CCA) for a credit card member and presumably some of the CCA is factored into the bonus. The 'hack' is to constantly apply, use, bin and then reapply for cards to maximize the bonus.

2) $1000 in airline fare isn't actually a $1000 liability to the airline, because that is the market price where as to them the cost price is going to be less... and as you suggest if they restrict it to a few seats per plane the cost price is even less.

Because so few people actually redeem their FFMs. They hoard them up. And then quite often, completely in the terms of the program, they don't earn enough and their balance gets wiped.

And yes, reward flights usually require you to pay tax, and for popular routes there may be only one FFM redeemable ticket per class per flight. Meaning you have to book ages in advance, choose less popular routes/times or be damn damn lucky.

The value is increased even further if you redeem the miles for first class tickets (which can easily be worth several thousand dollars, and which I suspect most people would never be willing to pay out of pocket for).
