*** Note: In 2018, many airlines changed their accounting principles to conform to new standards, which lead to some significant changes in the numbers reported compared to previous years. For the sake of clarity, many airlines provided recast 2017 results in their 10-K reports that
can be found in SEC’s EDGAR tool.
Note: Zero value might also mean data not reported.
