Norwegian cruise line had a similar thing recently with emails going out with actual booking information. Basically identical to the frontier scam emails. I wonder if there’s some customer service software that’s being exploited that they both use.

Edit: some info from the NcL one with screenshots that look similar https://www.reddit.com/r/NCL/comments/1x2q54e/warning_possib...

There was a post the other day that Amadeus (one of the major backend GDS systems) had been persistently exposing passenger information via a vulnerable endpoint since 2023

So that or similar other hacks

Came here to point that out. Several airlines, mostly from Asia, have sent notice of data breaches related to Amadeus software. Frontier appears to contract with Amadeus.

		This is why I love HN, looks like a solid root cause analysis.

Same in Australia with hotel bookings last week, even email formatting is the same as in Frontier's https://www.abc.net.au/news/2026-10-29/tas-federal-group-hot...
