Flying in during these times, are there certain requirements I have to have before a flight? Like will I need proof of a negative covid test or anything like that

Only if you're traveling out of country so if you need a passport you need a covid-19 test

Domestic flights you won't need anything, international flights you would have to check the requirements because it changes depending on where you are coming from. Mostly likely you'll be required to have a negative PCR test within 3 days of arrival.

I just flew in yesterday. No requirements, if you're flying within the US. However if you're coming in internationally, you're required a negative test 3 days prior to your arrival.

We didn't need anything special, just wear your mask. It was a pretty well marked airport, easy to navigate.
