The exception is the Blue Line from O'Hare International Airport. Single-ride fares from the airport will more than double, to $5 from $2.25, under the $1.39 billion budget that CTA president Forrest Claypool proposed. Someone riding to the airport on the "L," to meet someone at the airport, for example, then riding back within two hours, would only pay a 25 cent transfer fee, a CTA spokesman said.
