I noticed two new TSA changes in effect yesterday and one almost prevented me from getting through security. The first is the requirement of TSA that the name on your boarding pass EXACTLY match the name on the ID you are using to get through security.
Both my state of Hawaii ID and my passport list my first name, middle name, and last name. My Delta account has all of those plus 'Jr.' on the end because I am a Jr. TSA does not like this. They explained the rule change to me and let me go through anyway most likely because there was no one in line, but they really didn't want to.
I've decided to ask Delta to drop the Jr. from my account name since that will, in theory, be easier than changing the name on either of my forms of ID. What I wonder is the value of a suffix on your name. My passport lacks the suffix. But when you apply for a passport, you send in your birth certificate and they take the name from there. At least that's how it worked for me 10 years ago. So if the US Department of State doesn't think I should have Jr. on the passport, I don't think I want to change my state ID to include Jr. Thus, asking Delta to match up with my IDs.
So, make sure you ID names and ticketing names match. Otherwise, be prepared for hassle. Once I actually have the names matching up, I'm wondering if TSA will still be satisfied. Most all boarding passes I see have limited room for a middle name. We'll see, I guess.
Lastly, TSA seems to no longer require you to have your ID and boarding pass out when you walk through the metal detector. They seem to be fine with the first check at this point.
