Flybe bosses have met with UK Government officials in a bid to save the airline from collapse, according to reports.
The airline operates more UK domestic flights than any other and is reportedly in talks over potential emergency financing after suffering rising losses.
If it collapses it would be the second UK airline to fail in four months, following the demise of Thomas Cook.
According to Flybe's website, they operate 12 routes from Cardiff Airport.
Flybe have refused to comment on "speculation" and released this statement:
Spokespeople for two government departments issued the same statement, saying: "We do not comment on speculation or the financial affairs of private companies."
Cardiff Airport's Chief Commercial Officer, Spencer Birns, said: "Flybe operations into and out of Cardiff are operating as normal - we understand that there are no disruptions to scheduled services across any of their UK network.
"Our customers are our primary focus, and we will endeavour to keep them fully updated. We advise any customers with enquiries regarding their travel to contact the airline directly. Alternatively, follow live flight information on our website at www.cardiff-airport.com/live-flight-information/ and keep up to date on Twitter @Cardiff_Airport."
In February 2019 the airline was bought by a consortium led by Virgin Atlantic following poor financial results. Connect Airways, which consists of Virgin Atlantic, Stobart Air and Cyrus Capital, paid £2.2 million for Flybe's assets and operations.
Flybe is Europe's largest regional carrier, flying around eight million passengers a year to 170 destinations across the continent.
Around 2,000 people are employed by the airline.
The airline began as Jersey European Airways in 1979, operating regional flights from Jersey.
Its route network grew and it was rebranded British European in 2000, before becoming Flybe in 2002.
