NEW YORK - The city says its "Fair Fares" program of half-priced MetroCards will only apply to monthly and weekly passes — not single rides.

Under the program, low-income New Yorkers will be eligible to buy a 7-day MetroCard for $16, and a 30-day card for $60.50.

But the lack of a single ride option has some transit advocates disappointed.

"We fought really hard to get here just to have the city subsidize and pay for half the fare and we'll be working hard to make sure all New yorkers, no matter if they want to do single fare or monthly, will have access to the reduced fare," said Stephanie Burgos-Veras of the Riders Alliance.

"Fair Fares" starts in January and is currently funded through June of next year.

The city will pay the MTA for the difference in revenue under the terms of the plan.
