Here is a service i have happily used in Penang countless times over the past years, The buses are air-conditioned, seats are comfy enough and the price is outstanding value. Usually my ride would be into the city center from the suburb but I have ridden as far as the airport, though you would be better off with a ride-hailing service like Grab for a longer haul like that. Anyhow, you are probably wondering what my typical 15 minute ride downtown costs and it comes in at 1.40 MYR ($0.40 CAD). This price has not changed in 10 years or more. In Canada, the same type of trip costs 8 times as much!
