With nearly 3 million miles I have obviously given United a lot of business. However, their pandemic response has been pathetic. We need more than wings and engines to keep us safe now. It is not acceptable to pack planes as in the past. United can denigrate these concerns but, yes, I want them to do EVERYTHING they can to protect me. Until they show that they are dedicated to safety, don't fly United.
By comparison, some airlines show that they understand and are working to protect us and reassure us that they care about the health of their customers. With all the other disruptions we now endure to protect our health, why would I risk packing onto a plane full of people who obviously don't care, much less in fully packed seats.
On Zoom calls with colleagues across the country, I hear horror stories of packed flights and loose enforcement. Those friends have now reached the same conclusion. Some people may not want to "believe" in COVID, but I don't want to fly with them.
Also, don't tell me "at least United is better than American." It is not good enough to be better than the very worst.
