The public transit system in Frankfurt consists of several carriers who all utilise the same fare system. Therefore, one ticket is valid for a journey which may include several modes of transit run by different operators.

The fares are paid in advance of travel at a ticket vending machine or on board a bus. There are no turnstiles or other controlling barriers - passengers therefore have responsibility for ensuring they have a ticket. Plain-clothes ticket inspectors are employed and carry out checks to ensure passengers have paid.

If found to be travelling without at ticket, then they are required to pay an increased fare of €40. A trip within Frankfurt costs between €1.50 and €2.20, and a journey to the suburbs outside Frankfurt costs between €3.60 and €6.75 approx.
