It’s Friday, Friday, Gotta get down on Friday! Let’s see what’s up in the frequent flyer blogosphere….

Rapid Travel Chai writes about some expansions to the TSA PreCheck program, including new participation by Virgin America and the Philadelphia airport. Also, it appears that PreCheck is now working on some international itineraries. Cool.

Lucky writes about the changes that Delta is making to its partner mileage earning charts. There is a lot of spin on this issue by the Delta marketing folk over at FlyerTalk. I’ll probably wait to see what people are saying before I comment on it next week.

Citi is targeting the people who are using its ThankYou Network cards most heavily and shutting accounts down and confiscating earned points. FrequentMiler has some thoughts on that.

Some good stuff planned for next week! Stay tuned and have a great weekend!
