The DART Big M Block is a fare structure used by the Dallas Area Rapid Transit system that lets you ride multiple bus and rail trips within a set time window for one price

The DART Big M Block is a pass option offered by Dallas Area Rapid Transit (DART), the public transportation agency serving the Dallas-Fort Worth region. Instead of paying per trip, you buy a pass that covers a certain number of rides or a time period. The "Big M" refers to the Dallas metroplex, and the block structure means you get a defined amount of travel for a fixed cost.

DART offers several pass types, and the Big M Block is one way to reduce what you pay if you ride regularly. The exact price, number of rides included, and time window vary depending on which pass type you choose and when you purchase it. You use the pass on buses, light rail (the Red, Blue, and Green Lines), and the Trinity Railway Express commuter rail.

Key Takeaways

  • DART pass options include daily, weekly, and monthly structures, each with different ride counts and prices.
  • You can purchase passes at DART ticket machines, online through the DART website, or at retail locations like convenience stores.
  • Passes work on all DART bus routes and rail lines, including light rail and commuter rail.
  • The pass is tied to a physical card or mobile ticket, which you tap or scan when boarding.

How to buy a DART pass

You can purchase a DART pass through several channels. The DART website (dart.org) sells passes online, and you can have them mailed to you or pick them up at a DART service center. Many retail locations around Dallas also sell DART passes, including convenience stores and grocery stores — the DART website has a store locator tool.

At DART stations and on some buses, you will find ticket machines where you can buy passes in person. You can also visit a DART customer service office directly. When you buy online, you typically receive a physical card in the mail or a digital pass on your phone, depending on the option you choose.

What types of passes DART offers

DART offers passes at different time intervals. A daily pass covers unlimited rides for one calendar day. A weekly pass covers seven consecutive days. A monthly pass covers 31 consecutive days. Each pass type has its own price, and the price can change, so checking the DART website for current rates is important before you buy.

DART also offers reduced fares for seniors (age 65 and older), people with disabilities, and Medicare cardholders. If you fall into one of these groups, you will need to show proof of your status when you purchase a reduced-fare pass. Students may also have access to discounted passes through their school or university.

How to use your pass when you board

When you board a DART bus or train, you tap or scan your pass card on the reader near the door or at the fare gate. The reader will beep or show a green light to confirm the pass was read. If you have a digital pass on your phone, you scan the screen the same way.

Each time you board, the pass registers one trip. Once you have used all the rides included in your pass (if it is a limited-ride pass) or once the time window expires (if it is a time-based pass), you will need to purchase a new pass to continue riding.

When a pass makes sense for your budget

A pass saves money if you ride DART regularly. If you take two or more trips per day on most days, a daily pass is cheaper than buying individual fares. If you ride most days of the week, a weekly or monthly pass usually costs less than buying daily passes separately.

To figure out whether a pass is worth it for you, count how many trips you typically take in a week. Then compare the cost of that many individual fares to the cost of a weekly pass. Do the same for a month if you ride year-round. The DART website shows current fares so you can do this math yourself.

What happens if your pass is lost or damaged

If your physical pass card is lost or stolen, contact DART customer service. Depending on how you purchased it and whether you registered it, DART may be able to issue a replacement or transfer the remaining value to a new card. Digital passes on your phone are safer because they are tied to your account and cannot be used if your phone is lost.

If your card is damaged and will not scan, bring it to a DART customer service office or ticket machine. Staff can often replace it on the spot or issue a new one. Keep your receipt when you buy a pass — it helps DART verify your purchase if there is a problem.

Frequently Asked Questions

Can I use a DART pass on all buses and trains?

Yes. A DART pass works on all DART bus routes, the light rail lines (Red, Blue, and Green), and the Trinity Railway Express commuter rail. One pass covers all of these services — you do not need separate passes for different types of transit.

What is the difference between a daily pass and a weekly pass?

A daily pass covers unlimited rides for one calendar day and costs less than a weekly pass. A weekly pass covers seven consecutive days and is cheaper per day if you ride on multiple days. Choose based on how often you ride: daily passes work best for occasional riders, and weekly or monthly passes work best for people who ride several days per week.

Do I need to register my pass?

Registering your pass online is optional but recommended. Registration ties your pass to your account, which makes it easier to get a replacement if the card is lost or damaged. You can register on the DART website after you purchase.

Can I transfer my pass to someone else?

A physical pass card can be used by anyone who has it, so technically you can give it to someone else. However, a registered pass is tied to your account, so transferring it may require contacting DART. Digital passes on your phone cannot be transferred because they are linked to your device.

What if I buy a pass but do not use all the rides?

Time-based passes (daily, weekly, monthly) expire after their time window ends, and unused rides do not carry over. If you buy a monthly pass and only use it for three weeks, the remaining rides are lost. This is why it is worth calculating your typical usage before buying a longer pass.
