On Wednesday, the Federal Aviation Administration decided drastic measures were needed to ensure resilience in the national airline system, and they took steps to shave 10% of all air traffic across the top 40 high-volume US markets. This comes at a time when air traffic controllers are showing signs of strain due to the ongoing government shutdown, which has crippled airports, limited flight operations, and seen TSA checkpoint lines trailing out the door. The 10% of flights affected are expected to impact thousands of travelers across the United States.
