The airline says it has researched demand for the new services

The company said its research shows the flights will meet the needs of both the business and leisure audience.

It is the second time the service to Liverpool has been tried out - last time it lasted for just six weeks.

The airline is also ending its services at Swansea Airport next month after passenger numbers failed to take off.

The two new budget services will run twice daily from Cardiff International Airport from 1 November.

Air Wales said its research showed the Liverpool flight will be welcomed by the many business travellers who commute from south Wales to the north.

Passengers will be able to fly from Cardiff to Aberdeen

It said the Cardiff to Aberdeen service was last year voted among the top 10 requested destinations for passengers travelling between the two cities.

Air Wales Chairman Roy Thomas said: "We've researched these routes well and are confident that their launch will fulfil a real need among the Welsh travelling public.

"Currently, travelling times between north and south Wales are lengthy and often inconvenient, but by launching this cost effective twice a day service, we hope to address this problem, while also opening up business and leisure opportunities in Liverpool itself."

The 45-minute Cardiff-Liverpool flight was last launched before Christmas 2003 but stopped after six weeks following a "lower than average take-up rate."

In April, the airline which was set up in 1999, also abandoned its first Europe destination - the twice daily Brussels flight - after just three months following a disappointing take-up.

But its domestic services continue to expand.

Viable

Last month Air Wales announced it was starting a three-times-a-week service to Dublin as well as a weekly flight to Norwich.

Earlier this summer, the company also announced it was pulling out of Swansea Airport from the autumn, saying the service was no longer viable.

Staff were told that up to 20 jobs will go and cheap flights to European cities such as Amsterdam and Dublin would end in October.

Cardiff International Airport has welcomed the launch of the new routes.
