Ym mis Medi 2019 cyhoeddodd Llywodraeth y DU ei phenderfyniad i rwystro datganoli Toll Teithwyr Awyr i Gymru er gwaethaf argymhelliad y Pwyllgor Materion Cymreig trawsbleidiol i’w datganoli’n llawn i Gymru erbyn 2021. Mae datganoli’r Doll Teithwyr Awyr hefyd wedi’i gefnogi gan bob plaid a gynrychiolir yn y Senedd.
In September 2019 the UK Government announced its decision to block the devolution of APD to Wales despite the cross party Welsh Affairs Committee recommending full devolution to Wales by 2021. The devolution of APD has also been supported by all parties represented in the Senedd.
