Not sure this is new. Delta has always had a line there for their Medallion Flyers {Frequent Flyers} and another line for those that did not travel often. Most frequent travelers probably didn't listen to the TSA folks anyway...since we knew to take our shoes at SLC but not at other airports. Not sure how this new system changes anything except maybe in the terminal where United and others are. Best of Luck.

Since anyone can go in any line, this article is misleading. You can and will still get stuck behind families (I know, because I did yesterday), or business people. People will naturally gravitate toward the shortest line. What they need to do is increase the efficiency of the screeners. Some are good, others seem to be in perpetual training.

Not to get too complicated, but where do occasional (non-frequent) travelers WITHOUT special needs go? I haven't flown since before the 2001 terror, but will this year. Won't have kids with me, and I don't have any special needs. Does that make me blue or green? I think the descriptions of the line criteria need to be fine-tuned just a bit.

I am a frequent traveler and I do thing this is a good idea. One thing you want to do when flying is going through security screening as fast as you can. Only airport I didn't have to take my shoes off is the little airport in Dallas but everywhere else is just as strictic as SLC.

"line clogging strollers"? My experience has been that TSA does more single handedly to facilitate clogged lines than anyone with a stroller. Take last Sunday morning for example: The airport was swamped. In the International Terminal the line of passengers waiting for screening wound all the way around the terminal and down the stairs -- yet TSA made a brilliant decision to continue using only one of its security scanners. Yes, there are people that use strollers that do clog lines. However, there are also people without strollers that do just the same. Maybe the author of this article is a stroller bigot. You Stroller Discriminator! You didn�t even distinguish between double strollers and single strollers. What about umbrella strollers vs. jogging strollers? You never mentioned once the difference between strollers with turning front wheels and strollers with set front wheels. What about strollers that lean a little left and strollers that lean a little right? Nevermind strollers that tend toward the center? Stoller users should unite and seek protected class status. Those little wheels are just so innocent and cute. This stroller McCarthy-ism under the guise of journalism must cease.

To get through the TSA security screening faster-- particulary in the spring and summer months--I'll just go through the security line in shorts and flip flops, with no belt on or anything like that.

That way I'm not setting off the metal detectors, and I can take off my flip flops really quick, and there's no need to have re-tie my shoes. That and I'm not holding up the line as long.

Let's see how people and the media react to a Black line. What does that mean?

Some people say that TSA stands for Thousands Standing Around, and in the beginning I too agree that there was an abundance of TSA screeners, but that is no longer the case. This Black Diamond idea may work, if there were enough employees to make it work. From my experience the designated lanes only last as far as the ticket reader, then its a mad dash to either of the 2 out of 6 lanes open. It's very frustrating as a frequent traveler to stand in an enormous line with only one or two lanes open, and I'm sure equally as frustrating for the screeners that have to try and get thousands of travelers through with minimal help. Perhaps the answer is better staffing?
