Thank you, luv_maui and Henry M. It wasn't clear that Upload was for more than just Covid test results, so I didn't initially click on it. Are there any requirements for the photos? We will likely just take them on our phones, if there isn't a size limitation.
We have decided to go with Carbon Health for our tests and are getting ready to schedule the four time slots. I can't find information on the Carbon Health site about a cancellation/refund policy. Do they require payment upfront? I am wondering what happens if we can't go for some reason, if Alaska changes the flight time, etc. I sent them a message and I called them today. I was on hold for 25 minutes and then it went right to voicemail, even though the repeating message told me I was next in line. So I don't have any answers yet.
