“We’ve overhauled our cleaning and safety procedures and implemented a new boarding and deplaning process to promote social distancing," spokeswoman Kimberly Gibbs said in an email. "Our flight to San Francisco had an additional 25 medical professionals on board who were flying for free to volunteer their time in New York. We’ve provided complimentary flights for more than 1,000 doctors and nurses in the past few weeks alone – and all passengers and employees were asked to wear face coverings, consistent with our new policy.”
