Public Transit Passes
Metro cards, day passes, rail tickets, and when transit products save time instead of becoming wallet clutter.
Buy the pass only after the route exists
A day pass is useful when the day has enough rides. It is wasteful when the hotel, meals, and sights are walkable.
Airport rules do not equal city rules
Airport express trains, regional rail, and local metro can use different tickets. Check before tapping a random gate.
Validate the ticket like a local
Some systems require validation before boarding. The fine can be higher than a week of fares.
Keep one backup ride
Transit is the default, not the religion. Weather, stairs, strikes, and luggage can change the answer.
