What You'll Learn

Domestic vs. international flight times
When travelling on a domestic flight, you will need a government-issued photo ID, whereas international flights require a valid passport and possibly a visa. It is also important to check the entry requirements of your destination country, as some countries require an entry or exit fee, which may need to be paid in cash or via an international credit card.
Domestic flights are typically shorter, ranging from 1-5 hours, whereas international flights are longer, often exceeding 5 hours. The shorter duration of domestic flights means travellers are more prone to temporary fatigue due to changes in air pressure, low cabin humidity, and disruption of circadian rhythms.
Due to the shorter duration of domestic flights, there is a sense of urgency and a more hurried boarding and disembarking process. Additionally, smaller airport terminals handling domestic flights may experience congestion during peak times, contributing to a chaotic atmosphere. In contrast, international flights tend to have a more relaxed atmosphere, with a diverse mix of tourists, business travellers, and families. The longer duration allows passengers more time to settle in, and the larger terminals handling international flights have more gate staff, contributing to a smoother experience.
When flying from Austin Airport, it is recommended to arrive at least 2 hours prior to your departure time during peak travel times of 5 am-8 am, 11 am-1 pm, and 3 pm-5:30 pm. Outside of these peak times, arriving 90 minutes before departure is sufficient. For domestic flights, arriving 2-2.5 hours early is generally recommended, while for international flights, arriving at least 4 hours early is advised.

Peak travel times
To avoid long lines and ensure a smooth travel experience during peak times, it is recommended that passengers arrive at the airport well in advance of their scheduled departure. The recommended arrival time for domestic flights is 2 to 2.5 hours before departure, while international flights require a minimum of 3 hours. However, some sources suggest arriving even earlier, up to 5 or 6 hours in advance, to account for potential delays and the small size of the airport relative to the number of passengers it handles.
The Transportation Security Administration (TSA) has implemented measures to address security checkpoint delays, including expanding and improving security checkpoints, installing new screening equipment and technology, and increasing staff. Despite these efforts, passengers have reported chronic understaffing issues and long security lines at AUS, so it is advisable to allow for extra time when passing through security.
To streamline your security screening process, you can sign up for TSA PreCheck at three locations in Austin, including on-site at the Clear Enrollment Center located at TSA Checkpoint 1. With TSA PreCheck, you may only need to arrive at the airport 1 hour before your domestic flight.

Delays and staffing issues
Austin-Bergstrom International Airport officials reported a 17% vacancy rate for air traffic controllers, a notable improvement from the previous year's 30% rate. However, this improvement may not be enough to prevent potential safety hazards. There have been multiple close calls on Austin's runways due to the small size of the airport's controlled airspace.
The FAA has been criticized for its slow response to addressing the staffing shortages and safety concerns at Austin Airport. The FAA is responsible for hiring and training air traffic controllers, and their delay in approving the airport to control a larger airspace has contributed to the issues.
To address the staffing challenges, the FAA reported the largest number of hires in nearly a decade in 2024, with more than 14,000 air traffic controllers nationwide and approximately 3,400 in various stages of training. These efforts are part of their work to reverse the long-term decline in air traffic controller staffing levels.
In addition to staffing issues, passengers have also reported delays and general chaos at Austin Airport since the COVID-19 pandemic. It is recommended that passengers arrive at the airport well in advance of their departure time, with suggested arrival times ranging from 90 minutes to 2-2.5 hours before a domestic flight and 4 hours or more for international travel.

Outside of these times, passengers are advised to arrive 90 minutes before departure. However, passengers using general TSA screening for domestic flights should arrive at least 2.5 hours before their departure time, and 3 hours before for international flights.
To skip the long security lines at AUS, passengers can sign up for TSA PreCheck at three locations in Austin: at the Clear Enrollment Center, located at TSA Checkpoint 1; at 7010 W Highway 71 in Oak Hill; or online at TSA.gov/precheck. With TSA PreCheck, passengers only need to arrive at the airport 1 hour before their flight.
TSA PreCheck is a trusted traveller program that allows members to undergo an expedited security screening process at select airports, including AUS. Members can keep their shoes, jackets, and belts on during screening and don't need to remove their laptops or liquids from their carry-on bags. The program is designed to speed up the security process for trusted travellers and reduce congestion at airport security checkpoints.
The TSA PreCheck program is open to US citizens, nationals, and lawful permanent residents who are over 12 years old. To enrol, individuals must provide basic personal information, fingerprints, payment for a non-refundable application fee, and valid identification. Once approved, membership is valid for five years.

Construction and expansion
The Austin-Bergstrom International Airport has embarked on a multi-year expansion, development, and improvement program called Journey With AUS. The program's overall scope and budget are still in development, but it aims to meet the current and future needs of the growing region while elevating the passenger experience with an authentic Austin and Central Texas feel. The improvements will be funded through various means, including airport cash reserves, airport revenues, revenue bond proceeds, and Federal Aviation Administration grants. Notably, no local Austin taxpayer dollars will be used to fund the program.
The Journey With AUS program includes several projects that are currently in different phases of development and construction. One key project is the expansion of the Barbara Jordan Terminal, which will involve the addition of the new Arrivals and Departures Hall (A/D Hall). The A/D Hall will serve as the primary pickup and drop-off point for passengers, with an estimated cost of $820 million for construction. The total cost of the terminal expansion is expected to be $865 million, and construction is estimated to be mostly complete by December 2029. The A/D Hall will provide additional space for airline check-in counters, domestic baggage claim, and concessions such as stores and cafes. To facilitate this expansion, the Red Garage will be removed, and the first 3,000 parking spaces are set to open in 2026. The Yellow Garage is scheduled for completion in 2027.
Another project under the Journey With AUS program is the design and construction of a new Central Utility Plant (CUP) and associated chilled water thermal energy storage (TES). This project aims to provide reliable heating and cooling for the airport as it continues to expand. The new CUP will include chilled and hot water hydronic piping to the existing Barbara Jordan Terminal, along with chillers, cooling towers, pumps, control systems, and utility connections. The project has an estimated cost of $162 million for design and construction services, and construction is expected to begin in 2025.
Additionally, the Austin-Bergstrom International Airport has completed the construction of a second airplane fuel facility to meet the projected demand increase of 3% to 5% annually over the next ten years. The airport has also made progress in surface parking, with Phase 1 opening with Economy Lot H in late 2024, while Phases 2 and 3 are currently in the design phase. Furthermore, the airport has designed, built, and leased a new flexible cargo facility with airside access and space for trailer staging and employee parking. This project is substantially complete, with the facility beginning operations in 2024.
