The J.D. Power 2014 U.S. Credit Card Satisfaction Study concludes that American Express and Discover have the highest customer satisfaction of any credit card issuers.

The study measures customer satisfaction with credit card issuers by examining six factors:

interaction
credit card terms
billing and payment
rewards
benefits and services
problem resolution

American Express has been #1 for all eight years of the study, and this year for the first time, it was tied for the top spot with Discover.

Interestingly, overall satisfaction with credit cards is at a record-high, surpassing last year's record high.

Yesterday I wrote that Citi ThankYou Points had added Air France Flying Blue as a 1:1 transfer partner.

That's big news because there are some amazing high value uses for Flying Blue miles, and ThankYou Points are so easy to earn from the Citi ThankYou® Premier Card with its 40,000 point sign up bonus and 3x category bonus on travel and gas purchases.

When I was researching that post though, I couldn't find Flying Blue's complete award chart.

You can still pay United's award prices from January 2014 and before for premium cabin awards.

The catch is that you need to be changing an existing award that you booked February 2, 2014 or earlier.

Sunday I read a post on Gary Leff's blog that said that Iberia Avios had massively devalued its award chart for flights on oneworld airlines.

I looked up the Iberia award chart for oneworld flights and came to the same conclusion as Gary--that Iberia had put out a new, worse award chart. I wrote a post Sunday and another yesterday about the changes and how to beat them.

It turns out my posts were mistaken. Iberia hasn't touched its award chart since November 2011.

The reason I was wrong is that I had misunderstood Iberia's program.

See above.

This is the twenty-eighth post in a monthlong series that started here. Each post will take about two minutes to read and may include an action item that takes the reader another two minutes to complete. I am writing this for an audience of people who know nothing about frequent flyer miles, and my goal is that by the end, you know enough to fly for free anywhere you want to go.

Most travel credit cards have an annual fee.

Well, this is embarrassing. As it turns out, there was no devaluation of the Iberia Avios program. The rates in this post have been consistent since November 2011.

Almost no one in the world knew the rates for Iberia Avios oneworld redemptions because they weren't bookable online. Thankfully this FlyerTalk thread and in particular these two posts set the record straight.

"I don’t know what the fuss is all about. These have been the same Avios amounts for Oneworld redemptions through IB Plus since 2011.

I get frequent reader emails asking whether you can open a second US Airways® Premier World MasterCard® with 40,000 bonus miles after first purchase and paying the $89 annual fee.

The US Airways® Premier World MasterCard® will disappear in 2015 when American Airlines and US Airways integrate their frequent flyer programs, so people understandably are rushing to get the card or get it again and get the bonus one more time.

If award space isn't available on a flight you want, keep checking. Award space changes all the time. This is a truism, but I have never tracked one route and flight for a few days to show exactly how true the truism is until now.

I've tracked First Class availability on the brand new Asiana A380 this month and next for the past few days. There were changes every day.

I started tracking the award space for selfish reasons.
