I truly don't understand why anyone would opt for any airline testing option at all (alaska's or otherwise) when covid tests are free for every single US insurance under the CARES act. People just like to pay for things you can otherwise get for free?
I've gotten covid tested in the US about ten times in the last couple months, across different clinics and labs, all free (either through a typical US insurance with high deductible but the copay covered under CARES act, or because the popup-covid test site doesn't take any money or info at all other than an email to send results). All results back under 2 days, same as private clinics since the processing labs are generally the same (LabCorp etc). Had I gone to these airline or private clinics fleecing people over something available next door for free it would've cost over $1k.
