Denver airport's security lines to undergo major change now

• The reshuffling follows decisions from TSA and DIA leaders to do "a comprehensive review of the security checkpoint operations," TSA officials said in a statement.

What it looks like:

• Regular boarding pass holders should head to DIA's south checkpoint on Level 5 and Concourse A bridge on Level 6 for general screening.
• TSA PreCheck passengers or travelers with premium flyer status should go to the north checkpoint on Level 5, where multiple screening lines await travelers.
• Passengers with Clear can enter the south or north checkpoints.

Of note: The north security checkpoint now offers a "Travel-Lite" lane for passengers with a single carry-on bag. Rolling luggage is not allowed.

Why it matters: The relief travelers have been looking for could finally be coming as officials brace for what's expected to be one of the busiest holiday seasons in recent memory.

Yes, but: The airport continues to battle confusion and chaos that arises from ongoing construction, staffing shortages and the threat of employee strikes.

Be smart: Airport officials are still advising that travelers arrive "at least" two hours before flights to make sure they have enough time to get through TSA screening.

What to watch: More changes could be coming. TSA spokesperson Lorie Dankers told Denver7 that officials will "keep tweaking the operation in hopes of being able to find the most efficient way to get people through the security checkpoint."
