Tribunal Challenge to Cardiff Airport Subsidy
A planned £205.2 million subsidy for Cardiff Airport is set to be contested by Bristol Airport at a tribunal scheduled for Monday.
Legal representatives for Bristol Airport are anticipated to argue that the scale of the Welsh government’s subsidy is unprecedented within UK aviation and constitutes a breach of competition regulations.
The Welsh government will respond during the tribunal proceedings but has previously defended its decade-long investment plan for Cardiff Airport, which has been under ministerial ownership since 2013.
The competition appeal tribunal is expected to continue for two days.
In April 2025, the Welsh government officially granted a subsidy valued at £205.2 million to Cardiff Airport, with £20 million already earmarked for expenditure in the current financial year. The total amount is planned to be distributed over a ten-year period.
Officials stated that the subsidy aims to support the development of new maintenance facilities, hangars, and cargo capacity. Additionally, new flight routes will be established, focusing on global aviation hubs and destinations that could contribute to Wales’s economic growth.
Following the disclosure of the subsidy’s size and specifics, Bristol Airport submitted an appeal to the competition appeal tribunal in July 2025.
Bristol Airport is expected to contend that the investment equates to a subsidy of £71.50 per passenger and that public funds would effectively be subsidizing leisure travel from Cardiff Airport.
The airport will assert that passengers and airlines could be diverted from Bristol Airport through means that are anti-competitive.
It will also argue that Cardiff Airport should have been more rigorously assessed as an "ailing or insolvent enterprise" during the subsidy review, a legal classification that would have triggered additional scrutiny before public funds could be allocated to support the business.
The Welsh government has previously indicated it will defend the legal challenge brought by Bristol Airport and stated its intention to "fight for our ability to invest" in Cardiff Airport’s "long-term prosperity and shape its economic destiny."
Bristol Airport said the Welsh government's subsidy "was unlawful, disproportionate, and would unfairly harm airport and airline competition."
It added that it would be "asking the tribunal to quash the subsidy decision made by the Welsh government, which it believes failed to lawfully apply the subsidy control principles, resulting in a subsidy that should not have been granted."
A spokesperson for the Welsh government stated that ministers would present their position "through the proper legal process."
"As the case is the subject of ongoing litigation, it would not be appropriate for us to comment further at this stage."
A panel of three, chaired by Ben Tidswell, will hear Bristol Airport’s appeal against the subsidy and the Welsh ministers’ response.
The hearing is expected to last two days, with a decision likely to be announced at a later date.
