Say where you are going and when, and find people whose dates and destination actually overlap.
Go to /connections and select the Travel companion tab.
Enter where you are going and your start and end dates. These are real fields, so overlap is a genuine date query rather than a text guess.
See people heading to the same destination in a window that overlaps yours.
Requests flow through the same connection inbox as every other kind.
Open Find a travel companion in the app (sign-in required).
