The transaction is being made by a newly formed subsidiary of Vueling, which will be incorporated as an Austrian company and run initially as a separate operation.
The deal is subject to customary closing conditions such as the European Commission competition approval.
The assets include up to 15 A320 “family aircraft” and “an attractive slot portfolio” at various airports including Vienna, Dusseldorf, Munich, Palma and Zurich.
The new company plans to employ approximately 740 former Niki employees to run the operation.
Willie Walsh, IAG chief executive, said: “Niki was the most financially viable part of Air Berlin and its focus on leisure travel means it’s a great fit with Vueling.
“This deal will enable Vueling to increase its presence in Austria, Germany and Switzerland and provide the region’s consumers with more choice of low cost air travel.”
More details about the new subsidiary’s branding and route network will be provided in due course, IAG said.
