Airports And Covid-19: Negative Test Requirements For Travel

The ongoing COVID-19 pandemic has brought about several changes in the aviation industry, including mandatory masks on flights and social distancing at airports. In addition to these measures, some countries have implemented requirements for incoming passengers to present a negative COVID-19 test result before departure. For instance, the US has mandated this for all international travellers since January 26, 2021, and China implemented a similar rule for flights departing from or transiting through the country. While the US considered extending this rule to domestic flights, the idea faced opposition from airlines, and it has not been implemented as of December 2024.

International arrivals to the US

The test result must be provided to the airline in the form of written documentation (paper or electronic copy) of the lab test result. The CDC specifies that the test must be a viral detection test for current infection with SARS-CoV-2, i.e., a nucleic acid amplification test (NAAT) or a viral antigen test. The test must be approved or granted emergency use authorisation by the US Food and Drug Administration.

In addition to the pre-departure testing requirement, the CDC advises that international travellers get tested again three to five days after arrival and stay home for seven days after travelling.

Domestic flights in the US

As of January 2022, the US does not require a negative COVID-19 test for domestic flights. However, US officials are considering implementing this requirement, according to Transportation Secretary Pete Buttigieg. The Centers for Disease Control and Prevention (CDC) is currently having an "active conversation" about the potential mandate. CDC Director Rochelle Walensky has stated that additional screening in airports could help detect asymptomatic spreaders, and reduce the spread of the virus.

In November 2021, Senator Dianne Feinstein introduced a bill that would require passengers on domestic flights to be vaccinated, provide a negative COVID-19 test, or show proof of recovery from the disease. This was in response to concerns about the potential for holiday air travel to contribute to a surge in COVID-19 cases. However, the bill has faced opposition from airline CEOs, who argue that vaccine and COVID-19 testing mandates would be impractical and could bottleneck the domestic travel system.

Currently, the Transportation Security Administration (TSA) requires all domestic travellers to wear masks. This mandate was signed by President Biden in January 2022 and applies to airplanes, subways, and taxis. International travellers entering the US are required to show a negative COVID-19 test or proof of recovery.

Transit flights through the US

If you are transiting through the US, the rules are the same as for travelling to the US. This means that, regardless of your nationality or vaccination status, you will need to show a negative COVID-19 test result (taken within two days of departure) or proof of recovery from the virus (within the last 90 days) if you are over the age of two. This rule also applies if you are travelling from the People's Republic of China, including the Special Administrative Regions of Hong Kong and Macau, via third-country transit.

The US does not have a 'sterile international transit' policy, which means that even if you are only connecting flights, you must follow the same entry requirements as if you were entering the country.

It is important to note that each country makes its own rules, and requirements can change quickly. It is always best to check the latest information for the specific country you are travelling to or transiting through.

Testing difficulties

Travel advisor Kimberly Sargen points out the inconsistencies in testing procedures across different states, counties, and cities, which can make it challenging for travellers to obtain tests while on the go. The proposal to require negative COVID-19 tests for domestic flights also raises concerns about its effectiveness in curbing the pandemic, as other forms of travel, such as driving, are not subject to the same testing requirements.

Furthermore, travellers have expressed worries about the feasibility of finding testing sites, especially in smaller towns. The type of test required, whether PCR or antibody, and the criteria for testing, also add to the confusion and complexities.

Another challenge is the short time frame for obtaining test results. While some tests may take longer to process, travellers may need to adjust their schedules to ensure they receive their results before their departure. This uncertainty can cause anxiety and inconvenience for those planning their trips.

Additionally, the accuracy of COVID-19 tests is a concern. False negative rates can be high, especially for home tests that are less invasive and less accurate than PCR tests. On the other hand, false positive rates are typically low, but even a small percentage can impact a significant number of people when testing large populations.

To address these testing difficulties, some airports have implemented on-site testing facilities. However, this adds an extra layer of complexity to airport operations and can be a costly endeavour. Overall, while testing can be a valuable tool in the fight against the pandemic, it also presents a set of challenges that airports and travellers must navigate.

Testing mandate opposition

The proposal to require negative COVID-19 tests for domestic flights has received mixed reactions from local airport managers. Some airports have expressed concerns about the practicality of implementing such a mandate, acknowledging the challenges and difficulties it would pose. The Santa Barbara Airport, for instance, stated that while they would conform to the protocols to ensure the safety of travellers and the community, they recognised that it would be a challenging task.

The travel industry, including major US airlines and travel associations, has pushed back against pre-travel testing requirements for vaccinated international travellers. They argue that the mandate does not align with the current threat posed by COVID-19 and that it is detrimental to the US economy. Nick Calio, chief of Airlines for America, asserted that the testing requirement is negatively impacting the fragile US economy. Similarly, Roger Dow of the US Travel Association highlighted the disproportionate harm faced by the travel industry due to this mandate, noting that competing countries have removed such requirements and are now attracting more global travellers.

Travel adviser Kimberly Sargen questioned the effectiveness of testing only airline passengers, arguing that it fails to address the potential spread of the virus through other forms of travel, such as driving. She also pointed out the inconsistencies in testing accessibility across different states, counties, and cities, which could create obstacles for individuals seeking tests.

Boeing raised concerns about the economic implications of the proposal, while medical experts, such as Dr William Schaffner, an infectious diseases specialist, questioned the utility of testing international arrivals when COVID-19 is already prevalent within the US.
