Cardiff Airport says it's secured CityJet, part of the Air France airline group, to operate the Glasgow and Paris (Orly) routes and fill the breach left by Flybe.
CityJet will start serving the routes in January.
Flybe announced, earlier this month, it will be withdrawing the routes because of the reorganisation of its business.
Managers also say from the start of the summer schedule flights to Edinburgh and Jersey will be added.
Cardiff Airport’s Chief Executive, Jon Horne:
'This is fantastic news and I’m delighted CityJet has responded so quickly to pick up these vitally important routes from Cardiff Airport.'
'We’re very pleased that there will be continuity in our services to Glasgow and Paris for the tens of thousands of passengers a year for whom these routes are vital.'
The news that Cardiff Airport is to benefit from new routes to Germany and the Caribbean has been welcomed by the Airport's Chief Executive as an "encouraging" development.
The ongoing success we have in attracting new services means the hard work of the team here is paying off.
It is also encouraging that airlines and tour operators are making these commitments to Cardiff Airport and Wales and this gives us confidence that we are on track to achieve our longer term goals.”
Cardiff airport is to benefit from new routes to Germany and the Caribbean.
Europe’s largest airline group has launched a low-cost route to Dusseldorf from Cardiff starting in Spring 2014, while luxury Caribbean tour operator, Sandals, is introducing its first Barbados flight from Wales.
Germanwings, owned by Lufthansa Group, will first take off from Cardiff for Dusseldorf on 5th April, with flights departing on a weekly basis. The two-week Sandals flight to Barbados departs on Sunday 9th March.
This news follows Vueling’s winter programme expansion from Cardiff, with additional flights to Spanish airports, Malaga and Alicante, operating all year round, and Flybe’s addition of ski flights to Chambéry, Lyon, Grenoble and Geneva.
Cardiff Airport have been making progress in growing the number of flights and destinations. This new money will help them further improve the facilities at the airport and make sure the facilities for passengers are to the standards required for the 21st century.
Together with our investment in refurbishment and the new shuttle bus service, this programme of improved facilities and modernisation is part of our vision to create a high-quality airport of which Wales can be proud. The improvements will also make the airport more attractive to airline operators.
Improvements are set to be made at Cardiff Airport after the Welsh government confirmed it would supply it with a £10m loan.
The money will be used for a new security area to accommodate new technology and more passengers, a new taxi booking service in arrivals and improved drop off and pick up areas.
The loan will be repayable over 12 years and further improvements will be introduced after the first phase.
Passengers flying to and from Cardiff Airport experienced some delays and disruption today, after a technical glitch at the UK's main air traffic control room. Cardiff was one of the airports affected by the problems earlier this morning. Alexandra Lodge reports.
National Air Traffic Services (Nats) said the technical issue causing delays to flights across the UK has stemmed from its control centre in Swanwick, Hampshire.
"Due to a technical problem at Swanwick, we are currently experiencing some difficulty switching from night-time to daytime operation. This may result in some delays, for which we apologise.
"Engineers are working to rectify the problem as soon as possible."
The technical problem affecting the Swanwick air traffic control centre is unlikely to be fixed before 2pm.
Thousands of people have been affected by delays at major airports including Stansted, Heathrow and Gatwick.
The Association of British Travel Agents (Abta) said: "Technicians are working to try to resolve the issue but have advised that this is unlikely to be before 2pm today.
"Delays and flight cancellations at some UK airports are being experienced as a result. Customers due to travel today should liaise with their airline to establish if there are any changes to their flight arrangements."
The association said customers should be prepared for potential delays and advised them to carry essential items such as medication in their hand luggage.
There are delays of up to three hours at Cardiff Airport due to a technical problem affecting flights at airports across the UK. Passengers are being advised to check with their airline before travelling. Further flight information can be found on the Cardiff Airport here.
