The controversial Cardiff Airport Express T9 bus service has a new timetable from 1 April.
The new direct link and separate rail/ shuttle bus services from Rhoose station are run by New Adventure Travel, who took over last autumn from the previous operator.
Transport company FirstGroup has extended its deal with the government to run services on the Great Western rail network until 2019.
The new franchise covers a period in which a series of upgrades will take place along the Great Western network.
