@Paul8777 I have heard this same thing on here once or twice and it strikes me as very odd. Airbnb do not ask for id from those who accompany guests , we as hosts may but Airbnb do not , as far as I know. If the agent somehow found out the other travellers name it could only be because they sent it to you ,via messaging. I do not think Airbnb would be looking into your messaging unless some other alert was triggered. If they are doing so then this is a quandry for sure. I suspect there was a lot more going on there . It would be useful to get to the bottom of this and if it is or was Airbnbs mistake then ask for compensation , as others tell me loss of income is covered . .. H
