What are the current conditions for flying during COVID-19, particularly for Delta flights?

In a recent travel experience, an individual reported flying on a nearly empty Delta flight from Seoul to Seattle, with only one paying customer in Delta One. This led to discussions on the drastic changes in the aviation industry due to COVID-19, including low passenger numbers and the financial strain on airlines. Some commenters expressed skepticism about safety protocols, while others highlighted the advantages of traveling in premium classes during these times. The conversation touched on the mixed feelings towards the airline industry's treatment of customers prior to the pandemic.
