You know what government data you might want to look if you want to know the truth? the actual DOT data that shows that DL's airport employees get higher total compensation than AA/US or UA and are within single digit percent of WN even with the RR program.
For AA, UA, US, it isn't a small percentage... it's double digit differences in higher compensation for DL employees.
but let's face it that you want to see DOL data that isn't specific to the airlines and includes a lot of government workers since the highest percentage of union workers are government works while ignoring airline specific data that shows where DL employees rank.
and DL still has its own personnel at more stations that AA and UA.
those are airline industry specific facts that show why DL employees have repeatedly rejected further unionization and why the union tries so hard to ignore the whole truth in favor of manipulated statistics including an unwillingness to include DL employee profit sharing in their compensation comparisons.
when you make statements about what AA/US employees got in 2014 pay raises or for any historical period, there is no justifiable reason other than an attempt to hide the truth to exclude what DL employees received.
