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.

Major Impact on Airlines

Airline shares have traded cautiously as oil prices surged and officials flagged the possibility of airport shutdowns and four‑hour security lines. 

For carriers such as American Airlines Group (NASDAQ:AAL) and United Airlines Holdings (NASDAQ:UAL) which rely heavily on large domestic hubs and tight connection banks, bottlenecks at TSA checkpoints can undermine load factors, on‑time performance, and high‑yield corporate travel, pressuring margins just as they head into what was expected to be a record spring travel season.

The shutdown of some airports would have a large impact on airlines. Some other air carrier stocks to monitor include: 

  • Delta Air Lines (NYSE:DAL
  • JetBlue Airways Corp. (NASDAQ:JBLU
  • Southwest Airlines Co.  (NYSE:LUV
  • Frontier Group Holdings (NYSE:ULCC
  • Alaska Airlines Group (NYSE:ALK

Portfolio Strategies

For investors, the strategy starts with position sizing and selectivity rather than a panic exit from airlines. 

First, treat airline stocks as high‑beta trades on policy risk: if TSA call‑out rates push decisively above current levels or officials issue a formal closure warning, that is a clear signal to trim exposure or tighten stops on the most leveraged, domestic‑heavy names. 

Second, consider rotating a slice of capital toward less travel‑sensitive segments, such as diversified travel platforms or quality industrials, while keeping powder dry to reload if forced selling creates mispricing once a funding deal restores normal TSA operations.

Some examples of diversified travel platforms include Airbnb Inc. (NASDAQ:ABNB), Booking Holdings Inc. (NASDAQ:BKNG) and Expedia Group Inc. (NASDAQ:EXPE). Examples of industrials could include Eaton Corp. (NYSE:ETN) and Dover Corp. (NYSE:DOV). 

Finally, watch three indicators: TSA staffing metrics and call‑out rates, booking commentary from major carriers and any concrete progress in Washington toward resolving the funding stand-off. 

Together, they will determine whether the current turbulence in airline stocks becomes a brief air pocket — or the start of a longer reroute for a portfolio’s travel exposure.
