Flybe is to maintain a service between Cardiff and London City airport throughout the summer.
Up to two flights a day will run seven days a week from the start of the summer schedule on March 26 with one way fares starting at £34.99.
The route was introduced in October originally on a temporary basis while the Severn Tunnel was closed as part of a rail electrification scheme.
However the air link, which takes just over an hour, was extended due to strong demand from Welsh businesses and is now being continued as part of the airline’s summer timetable.
Flybe chief revenue officer Vincent Hodder said: “It is good news for the route that is receiving such positive support from the business community.
“Flybe prides itself on providing unrivalled regional connectivity and, as champions of regional air travel, it is heartening to see that this route is doing just that for Cardiff.
“We look forward to seeing demand continuing to grow, to allow it to become a firmly established route on our Cardiff schedule.”
Cardiff airport managing director Debra Barber added: “This important service has already seen many Welsh business professionals making the journey to London for the day – it’s proving to be a real time saver and an exciting prospect for companies who want to do business in Wales.
“A city service is an important link between both capitals, but it will only continue for as long as our customers support and utilise the route – so I’d encourage everyone to try the service.”
