BUS fares on the airport-to-city centre Airlink service are set to rise by 50p to £4.
The increase for adult tickets will come into force on Sunday, with return tickets now costing £7.
It is the first price hike to hit the service in five years.
Child fares are unaffected and Ridacard users can still travel for free.
Ian Craig, Lothian Buses chief executive, said the cost of buying new buses had forced the rise. He said: “We always try to keep prices as low as possible for our customers but we also have cost challenges to deal with, such as fuel and investing in new vehicles. Over the years, prices have gone up by a tiny fraction.” Trams will cost £7.50 return.
