Transportation Security Administration (TSA) warned on Wednesday that some U.S. airports might need to be closed due to the ongoing staffing crisis, as multiple airports are experiencing callout rates of 40% or higher.   

This is an acute stress test for airline stocks and any portfolio overweight in cyclical travel.

The catalyst is the partial government shutdown that has forced roughly 50,000 TSA officers to work without normal pay, triggering rising call‑outs and around 400 resignations so far. 

Acting TSA administrator Ha Nguyen McNeill told Congress in a hearing on Wednesday that airports could be forced to close checkpoints or even suspend operations altogether, as travelers are experiencing the TSA's highest wait times ever.

That kind of disruption reverberates directly through airlines' profit and loss statements: longer security lines, missed connections and flight cancellations all translate into refund costs, rebooking expenses, overtime and reputational damage that can weigh on near‑term demand.
