A safer, simpler way to get everyone into your group: • Your group is yours alone. New groups get a unique code nobody can guess, so two families on the same flight never end up in the same chat, and other passengers can't stumble in. • You decide who joins. Show your group's QR code to the people you want, or let them ask from nearby: you check that both screens show the same emojis, then tap Allow. Nobody gets in without it. • The code never leaves your group: it isn't broadcast, and it's sent only to the phones you let in, over an encrypted link. • Joining takes seconds: scan the QR code with the Camera or in FlightChat, tap a link someone sends you, or tap + → Join → Find Groups Nearby. • Rename a group and everyone in it sees the new name. • People you're no longer in a group with move to Past Chats, where you can still read your chats or delete them. • Two people with the same name? FlightChat now shows which group each one is in.
