I get where the airline is coming from - at least where I live, privacy law would definitely prevent the airline from releasing the personal details of another passenger, even in this situation. And I expect most people want it that way, even if its annoying in situations like this.
But having said they’d get in touch with the other passenger, the airline needed to go ahead and actually do that, ASAP.
(Yes, I’m ignoring the information security concerns because I’m sure those points will be well covered).
