A theory about Manifest season 4 explains how the passengers can stop the Death Date without following Ben’s Lifeboat theory. Surviving the Death Date – which is fated to happen on June 2, 2024 – is currently the biggest challenge facing Ben, Michaela, Saanvi, and all the other Flight 828 passengers. But though they know when it is, what they don’t have is a way past it.
That being said, the passengers do have at least a semblance of a plan for dealing with Manifest's Death Date. The deaths of Kory, Pete, and Jace was a teaching moment for the main characters that helped them realize how complicated surviving the Death Date really is. Zeke survived it, but the passengers may face a much more difficult road. The reason for that relates directly to the Lifeboat concept that’s been pushed by Ben and Saanvi. If they’re right, every passenger has to make the right call in the trials to come if any of them have a hope of surviving beyond June 2, 2024. If one fails the Callings, they could inadvertently doom the rest of them. In other words, it takes only one passenger to sink the Lifeboat.

The real way to beat the Death Date may not actually involve saving the Lifeboat, and could instead revolve around an individual's willingness to sacrifice
