Stuck in a Long TSA Line? Strategies to Rebook Your Flight

Lead

On March 28, 2026, travelers at several U.S. airports faced unprecedented TSA screening delays amid a partial federal government shutdown, forcing some passengers to miss flights and rebook. Waits topped four hours in some locations, while other airports reported near-normal processing times. Airlines have announced temporary waivers at affected hubs but are not universally required to accommodate missed connections. This guide explains practical steps to take at the airport and what policies and protections may apply.

Key takeaways

• TSA reported wait times exceeding four hours at some checkpoints during the shutdown; several large hubs showed multi-hour delays while others remained normal.
• Midday Friday reports showed Houston George Bush Intercontinental with 90 minutes to 2.5 hours, Atlanta Hartsfield‑Jackson advising at least four hours, Los Angeles International near five minutes, and Dulles reporting typical processing times.
• MyTSA app reporting was suspended during the shutdown, reducing one widely used source of official wait-time data.
• Several carriers (Delta in Atlanta, United in Houston, Southwest, Allegiant) announced temporary rebooking waivers that may waive fees or fare differences if replacements are same cabin.
• If you are in line, using an airline app to find and secure an alternate flight before your original departs can prevent a full no‑show cancellation.
• Basic economy fares are often nonchangeable; flexible fares and elite status or lounge access can ease rebooking at busy airports.
• Standard travel insurance policies typically do not cover missed flights caused solely by TSA delays; card protections and policy terms vary.

Background

The current partial government shutdown led to many federal workers being furloughed or working without pay, producing uneven staffing at Transportation Security Administration checkpoints across the country. TSA has said the result includes the longest security lines in agency history, with staffing gaps causing some terminals to struggle to keep throughput steady. The MyTSA app — a common public tool for monitoring wait times — was suspended during the shutdown, removing one source of real-time official data and pushing travelers to airport websites and social feeds for updates. Airline operations are already strained by seasonal demand (spring break) and high load factors, creating limited spare seats for rebooking in many markets.

Airlines and airports have few regulatory obligations to make passengers whole when a traveler misses a flight because they arrived late to security; the responsibility typically rests with the passenger unless the carrier itself delayed or canceled a flight. Nonetheless, carriers can and have issued targeted waivers when external factors disrupt large numbers of customers. Stakeholders include TSA (federal security agency), carriers and their customer‑service operations, airport authorities managing passenger flow, and passengers with varying fare rules and protections.

Main event

Reports from March 28 showed stark contrasts between airports. In Houston, midday wait times were reported at 90 minutes to 2.5 hours; Atlanta warned passengers to allow at least four hours for screening. By contrast, Los Angeles International reported roughly five minutes, and Dulles (Washington area) showed normal throughput. These discrepancies reflect local staffing levels and how many TSA employees were absent or working without pay that day.

If you arrive and encounter a very long line, travel reporters and industry sources recommend immediately asking airport staff whether alternate checkpoints or shorter queues are open, since walking a small distance can sometimes cut hours off your wait. If you are already in a slow-moving queue, open your airline’s app to search for other flights and, if possible, rebook before the original flight departs; otherwise the carrier may mark you as a no‑show and cancel remaining segments. Passengers who purchased basic economy fares should be aware these tickets are often nonchangeable, making rebooking harder without paying fare differences.

Some carriers implemented ad hoc measures at specific hubs. Delta issued a waiver at Atlanta allowing customers to adjust flights while still in line in certain situations; United announced a similar policy for Houston. Southwest and Allegiant said they were assisting customers who missed flights without charging rebooking fees, and Allegiant stated that the policy would remain through the shutdown. These company statements vary by airport and time, so affected travelers should verify terms directly with the carrier.

Analysis & implications

Operationally, extended TSA delays shift disruption from airlines into airport security processes, creating a gray area for passenger recourse. Airlines are not required to absorb rebooking costs when a passenger fails to reach the gate on time due to security lines, yet public relations and capacity pressures during peak travel can push carriers to offer concessions. The result is a patchwork of case-by-case solutions rather than a uniform industry standard.

For consumers, the episode highlights the value of fare flexibility and status: refundable or changeable tickets, higher cabin fares, elite loyalty levels, and lounge access materially improve chances of quick recovery from a missed connection. Travel insurance often excludes predictable or known issues and typically does not list security-line delays as a reimbursable cause; card protections and certain add‑ons may help but require careful policy review before purchase.

Economically, repeated or prolonged security bottlenecks raise costs across the travel ecosystem: airlines face crew and aircraft scheduling complexity, airports handle passenger-service burdens, and business and leisure travelers absorb time and potential replacement-transport costs. Politically, the shutdown’s direct effect on passenger movement increases pressure on policymakers to restore staffing or seek temporary measures to maintain airport throughput.

Comparison & data

These snapshots illustrate how localized staffing shortfalls drive wide variance in passenger experience on the same day. Travelers should treat airport-specific reports as more reliable than national summaries and plan with a margin that reflects local conditions and your ticket flexibility.

Reactions & quotes

“We are hearing airlines are trying to work with passengers as best they can,”

The Points Guy / Sean Cudahy (aviation reporter)

Sean Cudahy has advised that asking airport staff about alternate checkpoints and using airline apps to rebook are practical first steps when lines stretch beyond normal expectations.

“Missing a flight due to a long TSA line would not typically be included as a covered reason for reimbursement under standard travel insurance products,”

Allianz / Daniel Durazo (director of external communications)

Allianz’s statement underscores that many standard travel insurance policies exclude reimbursement for security-line delays, though exceptions depend on policy terms and timing of purchase.

“[Delta] allows customers to adjust their flight while in line without speaking to an agent”

Delta (airline statement quoted to media)

Delta and other carriers rolled out location-specific waivers that may waive fees or fare differences for rebooking within the same cabin, but terms and availability differ by airline and airport.

Unconfirmed

• Reports that airlines routinely held flights beyond scheduled boarding for large groups delayed by TSA have been anecdotal and vary by airport; comprehensive data on how often this occurred is not publicly confirmed.
• Any specific timeline for when TSA staffing levels will return to normal depends on political developments and has not been officially announced.

Bottom line

If you encounter an unusually long TSA line, act early: check alternate checkpoints, use the airline app to locate and secure an alternate flight before your original departs, and use any airline affiliations or lounge access to reach customer service faster. If rebooking options are limited, consider non‑air alternatives such as driving or rail depending on cost and schedule flexibility.

Document your experience (timestamps, photos of lines, staff names if possible) and ask the airline about waivers, refunds or vouchers; review travel insurance and card benefits promptly. With uneven airport conditions during the shutdown, planning for extra time and choosing more flexible fares remain the most reliable protections against being stranded.
