U.S. airline earnings came fast and furious last week, and by Thursday, the six largest carriers had given their fourth-quarter and full-year 2020 reports to analysts. And after a ghastly 2020, there's still so much unknown about this year. American still is the largest airline, but it could furlough or lay off employees again. JetBlue still has its sights set on London (although we're not quite sure where). Hawaiian doesn't know when it will return to Australia and New Zealand. The 737 MAX is now just another of Boeing's problems, with its 777X program delayed and 787s requiring inspections.
