American Airlines has just become the first U.S. air carrier to offer at-home COVID-19 test kits to passengers ahead of domestic flights. Beginning Wednesday, customers set to fly to states with coronavirus-related travel will be able to purchase a LetsGetChecked kit online starting Saturday for $129, according to ABC News. Although testing via the kit is not a requirement for American Airlines travel, those who wish to participate will do the nasal swab at home, send it in for lab analysis and receive their results within two days of the sample arriving at the lab.
