Flybe is to operate up to four ‘rescue flights’ a day between Cardiff and London City Airport during the six-week closure of the Severn Tunnel later this year.
The airline said it will operate up to four flights on weekdays and two a day on weekends.
The tunnel is scheduled to be closed from September 12 to October 21.
Flights are available to book now, starting from £34.99 one-way.
Chief revenue officer Vincent Hodder said: "We have pulled out all the stops to ensure that customers wanting to travel between the two capital cities of Wales and England still have convenient and affordable travel options during the period when the Severn Tunnel will be closed and there will be no direct rail link.
"Flybe champions regional air travel and we hope these rescue flights will help alleviate the travel woes of the thousands of passengers displaced by the loss of the region’s direct rail services."
