London underground and bus fares will increase by an average of 2.5 percent across the city’s public transport network next year, while all-day tariffs for Oyster card holders will decline by as much as 31 percent.

Single tickets for adults traveling between zones 1 and 3 will increase 2.1 percent to 4.80 pounds ($7.60), while commuters using the city’s Oyster card discount will be charged 2.80 pounds for the same trip off peak hours, Transport for London said today.

“Freezing overall fares in real terms for next year allows us to hold down the cost of travel,” Mayor Boris Johnson said in a statement.

About 24 million trips are taken each day on London’s transport network by locals and visitors looking to navigate the capital and dodge the 170,000 vehicles that pay the city’s congestion charge.

Fares for all-day travelers between zones 1 and 5 will decrease 4.90 pounds to 10.90 pounds, as part of Johnson’s plan to support part-time workers in London by as much as 600 pounds a year, Transport for London said. To make up the cost, prices for non-discounted all-day travel — used most regularly by tourists and visitors from outside the city — will increase by as much as 35 percent.

“The daily cap comes at a cost of about 20 million pounds,” Transport for London spokeswoman Vicky Morley said by phone. “We do obviously need to recoup that, so we’re looking at where you can adjust fares elsewhere, so the paper travel card has increased to help.”

Tourists would still be encouraged to purchase an Oyster card, a form of electronic ticketing, which would cost the traveler 11.40 pounds – including a retrievable 5 pound deposit – as a cheaper option than the 12 pound paper ticket price, she said.
