Changes to the TSA checkpoints at Pittsburgh International Airport take effect on Monday. The changes come just days before the enforcement period for REAL ID begins and ahead of the summer travel season taking off.

Travelers arriving at Pittsburgh International Airport Wednesday without a Real ID or another acceptable form of identification should prepare for possible additional screening. Starting Wednesday, federal Real ID requirement goes into effect and will be enforced by TSA agents at airports across the country.

Pittsburgh International Airport has made adjustments to its security checkpoint operations, coinciding with the approaching REAL ID deadline for air travelers.
