Adds detail and background from paragraph 3

Feb 27 (Reuters) - The European Commission has dropped previously announced interim measures against Lufthansa LHAG.DE as part of an ongoing antitrust investigation, it said on Thursday.

The Commission said last month that it would order the German carrier to reinstate charter airline Condor's access to Lufthansa's short-haul network to feed Condor's Frankfurt-New York route.

The order related to an investigation of a joint venture between Lufthansa, United Airlines UAL.O and Air Canada AC.TO, which the EU executive believes could restrict competition for flights between Frankfurt and New York.

The Commission had said Lufthansa should reinstate arrangements agreed in June 2024 that provided feeder traffic to Condor to and from Frankfurt, which had ceased to apply in December.

Further consideration of all evidence, however, had shown that not all legal conditions for the interim measures were met, the Commission said on Thursday.

"This comes without prejudice to the ongoing investigation in the main proceedings," it added.
