Lufthansa-owned Eurowings will cease operating its daily service to Stansted on October 26, two days before Laudamotion begins twice-daily services from the Austrian capital.
Laudamotion is based at Vienna and takes its name from its original founder, the Formula 1 racing driver Niki Lauda. It operated mainly as a charter airline until January this year, when it became insolvent.
A bidding war then ensued, with the Lufthansa Group showing an interest. However, Ryanair announced in March that it would acquire a 75% stake in Laudamotion and double its fleet from nine aircraft to 18.
