It didn't end up touching any additional trips because of the slide. I mainly wanted to protect a specific day, I had training due and didn't want training to place it on that day, which would have just been a normal day off otherwise. I see no reason why crew plan wouldn't have dropped touched trips though.

If the final schedules haven't come out, and you want to slide for May, you might still have time to work that out, but hurry, and don't be surprised if they won't this late in the process.
