DAL rolls reserves into days off. They have up to 6 golden X days that are scattered throughout their days off. Big difference here is that they can’t stack them in one block, but at United we have to stack ours in one block. They also have instances where they can be flown on a golden X day. I don’t know if there is add pay associated but saying DAL doesn’t have rolled days off is incorrect.

DAL doesn’t have different reserve rules for Basic and Global flying. They don’t have FDO, RDO or HDO- just X days (off days) and then days on reserve.
