Do I need to get a covid test before flying?

You do not need a test to fly, but, Wisconsin is borderline stupid so you may need to quarantine when you get there. 

Check it out, don't be surprised when you arrive.

My quess is not, but, they are liberals

When will the official churches start praying for the false prophet? Rapture is a heresy. One must hide within a small group (10-12 people according to saint Seraphim of Sarov from Russia, 10-15 people group according to saint Gabriel Urgebadze from the country of Georgia) in order to escape the unforgivable mark of the beast. No documents; documents are from Satan; burn them (even documents of deceased relatives). No electronics once you hid so that you won't be tracked (even an old broken unplugged TV set from 1970's will show the infamous evil flying antichrist using Tesla's ether). [Saint Vyacheslav Krasheninnikov] Mark of the beast is given with World Passport (grey plastic card with no name on it); antichrist will release prisoners / insane asylum people to help him mark everyone. Police will mark people on highways; food stores will mark people who steal marked food (because marked food can only be swallowed by a marked person who has three strands of DNA instead of two). Reject vaccines, temperature scans, COVID tests (or similar), etc. Don’t go into UFO to be “healed” by evil demons; demons never do good.

No, COVID tests are not required for domestic flights and are not required by either of those states.  You will need to wear a mask on the flight. 

Different airlines have different rules.   I would want one AFTER flying though

No.  But you need to wear a mask.
