you + two more.

no. you wave, you don't swipe, and there are no hearts. the unit is a crew, not a match. people matching for solo travelers exists but it's off by default and lives in settings.

because every trip carries one. when someone posts a trip they pick the airport they fly from, and you pick up to four of your own — so the feed is simply the trips leaving from yours, on dates that overlap with yours.

you decide who joins your trip: every request comes with a profile and can be declined without explanation. after a trip, the crew privately answers one question — "would you travel with them again?" — and that count is what you see on a profile. reporting and blocking are one tap, and a block is two-way.

no. nearby works on approximate distance, never a pin on a map, and only while you have it switched on. you can be invisible to locals and visible only to people who are traveling, or turn the whole thing off and still use groups.

three to travel. two people is a plan, three is a trip — one to book, one to drive, one to find the place with the good food. that is the whole idea: you + two more.

no, and there never will be. a person is not a restaurant. the only signal is how many of the people who actually traveled with someone would do it again.
