A new day pass could soon allow CTA, Metra and Pace users to pay for rides across all three systems’ buses and trains, a step toward long-awaited complete integration of fares among the region’s transit agencies.

Metra’s board Wednesday approved creating a new Regional Day Pass that would allow riders unlimited trips for one day across the CTA, Metra and Pace. The measure still has to be approved by the CTA, Pace and the Regional Transportation Authority at meetings later this month, but if passed, the program would be tested for up to six months.

The move comes as the transit agencies are still looking to bring back riders from pandemic lows and adjust to changing demand, as riders commute less often to Loop offices and look to take buses and trains for other types of trips. It marks the latest attempt to adjust fares, following the creation of a monthly pass that can be used across the transit systems and Metra’s overhaul in February of its fare zones.

The pass would cost between $10 and $16 on weekdays depending on the length of the trip on Metra, where fares are based on the distance traveled. Weekend passes would be a flat $10. Reduced weekday fares would also be available.

The new pass is expected to be available for purchase this year, though the exact date will depend on when the Ventra vendor finishes development and testing. It would be available in the Ventra app, and valid until 3 a.m. the day after it’s first used.

The RTA said the pass prices come out to less than the cost of paying for both a CTA day pass and a Metra day pass. The RTA would reimburse the transit agencies up to $1 million for the difference in price.

The RTA said the ability to integrate fares across the systems, provide frequent service and maintain relatively low fares in the future will depend on getting additional funding from the state to fill a $730 million budget gap expected when federal COVID-19 relief funding starts running out in 2026.

“This agreement is a major step forward for integrating fare policies and products between the region’s transit agencies as we look toward a post-pandemic future of changing travel patterns and more inter-connectivity between agency services,” RTA officials said in the statement.
