Can you tell this when booking your tickets? It isn't a detail I've seen using most travel websites or even an airline's own app.

Last minute airplane swaps are not uncommon, so such a feature doesn't necessarily help.

You probably can figure it out with some sleuthing. For one example, SeatGuru records every airline fleet's different plane types. Once you have airline + plane type for each of that airline's routes, I bet you can dig up the engine type from that info.

There's often also press about it - eg https://www.geaviation.com/press-release/genx-engine-family/...

If it has GEnx engines you have little to worry about.

GE has also had problems with the GEnx including a double engine failure on a 787.
