Earnings Per Share [Abstract] |
Loss Per Share | Loss Per Share Basic loss per share is calculated by dividing net loss by the weighted average number of shares outstanding. Diluted loss per share is calculated similarly but includes potential dilution from restricted stock units, the crewmember stock purchase plan, convertible notes, warrants issued under various federal payroll support programs, and any other potentially dilutive instruments using the treasury stock and if converted metho d. Anti-dilutive common stock equivalents excluded from the computation of diluted loss per share amounts were 2.0 million, 1.8 million, and 3.4 million for the years ended December 31, 2023, 2022, and 2021 respectively. The following table shows how we computed basic and diluted loss per common share for the years ended December 31 (dollars and share data in millions):
