What would make flight sharing useful without feeling invasive?

We’re exploring a flight-sharing flow in PAIChat: when a flight confirmation is shared in a chat or connected email, PAIChat can turn it into a shareable flight card for the people you choose.

On travel day, it can keep that group updated when plans change, so no one has to chase flight numbers or send “did you land?” messages.

We’re trying to get the privacy boundary right: which details should be shareable, and which should stay private? Would you want automatic updates and if so, when should they begin and how often?
