Now sure if a four year old account in the name of John Smith decides to book a flight for four other people none of whom have an obvious connection to John Smith and he isn't on the booking then yeah very suspicious (potentially a compromised account).
It may not even have to do with the names on the booking. OP, did those tickets eventually get cancelled?
The most obvious trigger is just having had different accounts transfer points to a single account. Probably because the authorized user thing is a common workaround? Still think they just need to get rid of that avenue if it flags the account.
