How to Pay Less for Public Transit: Fare Caps and Free Transfers in Major U.S. Cities
Do you tap the same transit card every day and still pay full fare for every ride?
In New York, Los Angeles, Portland, and Indianapolis, the fare system may already owe you free rides — once your spending hits a daily, weekly, or monthly ceiling, the rest of your trips cost nothing.
That ceiling is called fare capping, and it works automatically. No pass to buy in advance, no form to fill out. But it only works if you pay the right way, and in some big cities it does not exist at all. Here is how it works, what each city charges, and the math that shows whether it saves you anything.
What fare capping actually does
Fare capping turns a pay-per-ride system into an unlimited pass — but only after you have ridden enough to earn it.
Every tap charges the normal single fare. The system keeps a running total, and once that total reaches the price of a day, week, or month pass, every further ride in that period is free. You never pay more than the pass price, and you never pay for a pass you do not use enough to justify.
That last part is the point. The old model asked riders to guess in advance whether a weekly pass would pay off. Capping removes the guess: light weeks cost little, heavy weeks cost no more than the pass.
The caps in five U.S. cities
Four of the five systems below cap fares automatically; the fifth caps daily spending only.
All five figures are current as of November 2026, from each agency's official fare page. Fares change — check the agency's site before you budget around a number.

Free transfers: the second discount most riders miss
A transfer window can turn a two-fare trip into a one-fare trip — and the window is generous.
In New York, a subway-to-bus or bus-to-subway transfer within two hours is free. Los Angeles gives two hours of free transfers on a TAP card. Portland's $2.80 fare covers unlimited rides for 2.5 hours. Indianapolis allows free transfers within two hours.
Two details catch people out. First, the free leg of a transfer does not count toward your fare cap in New York or Los Angeles — only paid rides do. Second, cash riders usually get neither benefit: pay cash on a bus in Portland and the fare covers one ride only, with no transfer at all.
Five rules that decide whether you actually save
1. Use the same card or device every time
The cap is counted per payment method, not per person. Your phone and the physical card in its wallet count as two different payment methods, even when they draw on the same bank account. Pick one — card or phone — and tap it for every ride. Splitting rides across two methods splits your progress toward the cap in half.
2. Don't pay cash
Cash fares never count toward a cap, and usually buy no transfer either. Los Angeles is explicit: cash riders are not eligible for fare capping at all. A TAP, OMNY, Hop, or MyKey+ card costs little or nothing to get, and it is the only way the ceiling applies to you.
3. Remember that free transfers don't count toward the cap
Only paid rides move you toward the ceiling. If your commute is a bus plus a subway on one free transfer, that is one paid ride toward the cap, not two. This is why a rider who transfers everywhere reaches the cap more slowly than a rider who pays per leg — and why the cap is a ceiling on spending, not a loyalty program.
4. Register your card where the weekly cap requires it
In Indianapolis, the daily cap works on any MyKey+ card, but the weekly cap only works on a registered one. An unregistered card stops at the $6 daily ceiling and never earns the $24.75 weekly ceiling. Registration takes a few minutes in the app or online, and it also protects your balance if the card is lost.
5. Check the reduced-fare cap if you qualify
The ceilings are lower for seniors, riders with disabilities, and students — and the savings are proportionally bigger. In New York, registered reduced-fare riders cap at $17.50 a week instead of $35. In Los Angeles, seniors and riders with disabilities cap at $2.50 a day and $5 a week. In Portland, Honored Citizen and Youth riders cap at $28 a month instead of $100. In Indianapolis, half-fare riders cap at $3 a day and $12.15 a week. If you qualify, enroll before you ride: the reduced cap only applies to a registered reduced-fare card.
The math: when capping beats pay-per-ride
Capping is a ceiling, not a discount — and for light riders it saves nothing.
Take a New York commuter who rides twice a day, five days a week. That is 10 rides at $3.00, or $30 — under the $35 cap, so capping saves exactly $0. Add two weekend trips and the week becomes 14 rides: $42 without a cap, $35 with one. The saving is $7 a week, or about $364 a year.
Portland tells the same story on a monthly scale. A daily commuter making 40 trips a month pays $112 at $2.80 a ride — but the $100 monthly cap stops the meter at 36 trips, saving $12 a month, about $144 a year. Ride fewer than 36 times and the cap never kicks in.
Los Angeles is the subtlest case. Ten rides a week costs $17.50, just under the $18 weekly cap — so the weekly cap rarely helps a standard commuter. The daily $5 cap does the work instead: three rides in one day would cost $5.25, but the cap holds it at $5.00.
The pattern holds everywhere: count your rides first, then check whether you cross the threshold. If you don't, the cap is irrelevant — and a monthly pass would be a worse deal still.
The cities that still don't cap: buy the pass in advance
Chicago and Boston still run on the old model: the discount only exists if you buy it before you ride.
Chicago's CTA charges $2.50 for the 'L' and $2.25 for buses, with a 1-day pass at $5 and a 30-day pass at $75. There is no automatic cap — tap a bank card every day and you pay per ride, all month, no matter how many trips you take. The 30-day pass pays off at 30 rides, so a daily commuter should buy it on day one.
Boston's MBTA charges $2.40 a subway ride, with a 7-day pass at $22.50 and a monthly LinkPass at $90. The monthly pass needs 38 rides to break even — about 19 round trips — so occasional riders should skip it and just tap.
If your city is not in either list, check its fare page for the words "fare capping" before assuming the ceiling exists.
Key Takeaway
Fare caps reward heavy riders and cost light riders nothing — but only when you tap the same card or device every time, skip cash, and, in Indianapolis, register the card. Count your weekly rides first: if you cross 12 in New York, 36 a month in Portland, or 9 a week in Indianapolis, the system starts paying you back.
The cheapest fare in your city may not be a pass you buy — it may be a ceiling you hit without trying.
