SciFiFilter FTL-ish Plausibility Check

In a discussion elsewhere on the internets a twist on a common science fictional transportation technology was proposed. A spaceship leaps from one point in space to another, but while it is instantaneous for the passengers, the transit actually takes some small amount of time longer than light would take to cover the distance (let's say the Planck time). Would the time delay prevent the violation of causality? It appears that everyone is staying in their light cones, what am I missing?

As an example, a spaceship bound for Alpha Centauri would engage the drive and disappear from our solar system. Without any intervening travel, it would reappear near that group of stars just over 4.37 years later.
I studied physics many many years ago and what little I mastered of Lorentz factors has long since dissipated.
Thanks for indulging my nerdly inquiry. If this were ever used in a story I wrote, MeFi would receive the acknowledgement it merits.
