Any time a carrier brings back IFE I'm happy, my neck gets stiff trying to watch on my personal device, and on longer flights with meals I don't want to share my tiny tray table.
I don't know what routes UA used the MAX on before the grounding but would this new IFE-equipped variant have the range for transatlantics where some carriers use 757s? It's still pretty common to have IFE when going TATL. It wouldn't be bad to have IFE on Hawaii routes either!
