Mastering negative tests I hope! It ain't nothing. Mass just wants you to fill out an agreement on their state website that you are being covid safe
If you are flying domestically there is no requirement to display a negative Covid test, although you may need to fill out an attestation that you will quarantine or test negative. However, if you are arriving in Boston, or connecting through, from an international location then you may need to show your negative Covid-19 test results (within 3 days) only if asked to do so after deplaning.
