Despite a spike in cases due to the omicron variant, the U.S. Centers for Disease Control and Prevention issued new isolation and quarantine guidance for the general population on Dec. 27, 2021.

In particular, the CDC shortened the recommended isolation time from 10 days to five for people who test positive for COVID-19 but are asymptomatic. Additionally, individuals with no symptoms or resolving symptoms can exit isolation after five days but should wear a mask for at least five more days. Individuals with a fever should continue to stay at home and isolate, though.

The CDC also issued new guidance for individuals who have been exposed to someone with COVID-19. In short, if you’ve been boosted or recently vaccinated, you should wear a mask around others for 10 days. Otherwise, you should stay home for five days and then wear a mask around others for five more days. In either case, you should test on day five if possible. And of course, you should get a test if you develop symptoms.

In issuing the new isolation and quarantine guidance, the CDC said “The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after.”

But, here at TPG, we have questions. The biggest: What does all of this mean for travel? Below, we’ll break down some specific questions, taking a look at what we know, what we don’t and what we’ll be watching out for in the coming weeks.

If I test positive abroad, can I now fly back to the U.S. sooner?

Under the U.S.’ current rules, it depends. You cannot enter the country by air if you continue to test positive unless you show a signed letter from a health care provider or a public health official stating you have been cleared for travel. So, regardless of the CDC’s recommendations, unless the U.S. changes its testing rules for entry by air, you will have to remain abroad until you test negative or obtain clearance from a doctor or other authorized official.

However, even if you have the necessary clearance, you could run into roadblocks with your airline. Many carriers — United, American, Delta and others — require you to attest that you do not have COVID-19 when you check-in online for your flight. If you test positive and you’re truthful, you likely won’t be able to check-in online. You could proceed to the airport and try to check in there with your documentation, but you still risk being denied boarding.

For that reason, be sure to plan accordingly in case you find yourself stuck overseas due to COVID-19.

Will the U.S. change its testing requirements for entry by air?

Currently, the requirements remain the same. Specifically, U.S. citizens, nationals and lawful permanent residents must show proof of a negative test taken within one day of departure, regardless of vaccination status, or obtain a signed letter from a doctor or public health official certifying they’re fit to travel with a positive test result.

These regulations mainly affect travelers entering the U.S. via air. They do not apply if you drive across the border or disembark a cruise in the U.S.

What do the recommendations mean for airline passengers?

As they exist now, most airline check-in policies will hinder COVID-19-positive flyers — even if those travelers have isolated for five days and don’t have symptoms — because they require passengers to attest during check-in that they haven’t recently tested positive for COVID-19. For example, Delta currently asks its passengers to commit they haven’t been diagnosed with COVID-19 within the past 10 days.

As such, the new CDC recommendations currently do little to help airline passengers get to where they’re going shortly after testing positive, even if they follow the isolation suggestions.

Will airlines change their policies for passengers?

So far, TPG is unaware of any changes to check-in policies or attestations to coincide with the new CDC guidelines. But, we will continue to monitor the situation and update our content accordingly.

We don’t think it’s a coincidence that Delta, JetBlue and Airlines for America — on Dec. 21, 22 and 23, respectively — wrote letters to the CDC, asking the organization to reduce its 10-day isolation and quarantine rules for vaccinated individuals who test positive for COVID-19. These letters cited the effect the lengthier recommendations were having on the airlines’ workforces, following a spate of canceled holiday flights that resulted from COVID-19 cases among crew. For example, here’s the letter from Delta:

On Dec. 21, Delta Air Lines became the first of three entities to write a letter to the CDC. The airline asked the organization to decrease the amount of time recommended for isolation of COVID-19-positive people who are vaccinated. (Image courtesy of Tori Bedford via Twitter)

The letters mainly focused on getting airline employees back to work sooner. So, it’s unclear whether the airlines will change their guidance for passengers.

Will I have to prove that I isolated or that I’m asymptomatic?

If you test positive and hope to procure the appropriate signed permission from a health care provider to reenter the U.S. before testing negative, you may have to prove you isolated for the proper length of time and that you aren’t presenting symptoms. The exact process will likely vary depending on the health care provider.

But, for domestic flights, testing isn’t required. So, it’s most likely that if airlines change their check-in attestations or commitments, it will still all be on the honor system. As such, it’s doubtful anyone will check whether you’ve isolated or whether you’re asymptomatic before a domestic flight.
