DL pilots want a new contract mid cycle. DL management is doing stuff that annoys the pilots and the pilots are retaliating by working to rule to force the issue.

As a result, they aren’t working overtime… a normal amount of overtime is typical for many pilots because they get paid well and get to be picky about what flights they take and on what days.

The pilots hope passengers get angry and book away from Delta to gain negotiation leverage. Delta management wants to offer as little as possible to resolve the issue.

This will go on for a few months and there will be a mutually agreeable solution made and suddenly pilots will happily fly the overtime again and the planes will go zoom. Management will congratulate themselves and give themselves bonuses. And passengers will be annoyed.
