Last time I flew was late January from East Coast to Las Vegas - less then 50% on each flight. Routed through Detroit, normally there are 4 departure boards full at 6pm local. Only two were filled and of the few pax in both DTW and LAS, many were wearing masks despite not knowing what good they may or not be at that time. I will fly if the company tells me to but reluctantly. I'll also pick my airlines and flights carefully. It doesn't help that United and Delta both pulled out of my close airport. That leaves American and Southwest with the airport authority saying flights are 10-20% full and the airport has dropped 95% pax since a year ago.
Recent 100% packed American 737 flights in the news haven't helped their case. Frankly, it amazes me that certain routes (NY-FL) are so full. Nothing is open on either end.
