Air travel in six months: What it will look like

Summer vacations used to mean wine tasting in Tuscany, backpacking in Southeast Asia or trips to the Grand Canyon.

But fears that airplanes could be a breeding ground for Covid-19 infections have wreaked havoc on the air travel industry.

"This could take several years before we're into our new normal of traveling," said Delta Air Lines CEO Ed Bastian.

Last Sunday, fewer than 640,000 passengers flew out of U.S. airports compared with more than 2.6 million travelers a year earlier.

With passenger demand in sharp decline, Delta, United and American parked hundreds of planes and posted their first quarterly losses in more than five years.

American Airlines said it expects its second quarter 2020 revenue to be down about 90% versus the second quarter of 2019.

The U.S. airline industry is in turmoil.
