The Consumer's Association has accused public transport operators of ripping off commuters.
The cost of using Iarnr€d €ireann's bus, rail and DART services is to increase by around 5% from mid-week.
Monthly tickets for Commuter trains will increase by €4.50.
The cost of Luas tickets is also increasing by 10 cent from tomorrow.
The Consumer's Association has said there is no justification for this type of increase.
