For the non Delta people:
Pilot payment was the retro/not retro/signing bonus we got at contract ratification. Basically back pay for 2019-22
Retro was 2023 contract rates retroactive to 1 JAN 2023, we were still working on 2019 rates through March.
Greivance Settlement - should be self explanitory.
Miscellaneous is where they pay us for physicals, etc. (contract rate, auto pays when you upload a new cert)
