* Lufthansa says has dropped demand for some concessions
* Some 890 flights cancelled by strike on Wednesday
* Corporate customer Siemens calls for talks to resume
* Lufthansa shares down 2.5 percent (Recasts with new wage offer)
BERLIN, Nov 30 (Reuters) - Lufthansa said it hadmade its German pilots a new wage offer to try to end strikesthat are causing hundreds of flight cancellations and costingmillions of euros a day.
The airline said on Wednesday it had dropped demands thatwould see pilots working more hours in exchange for a wageincrease. It is still offering to raise pilots' pay by 4.4percent in two instalments in 2016 and 2017 and make a one-offpayment worth 1.8 months' pay.
Union Vereinigung Cockpit has called for an average annualpay rise of 3.7 percent for 5,400 pilots over a five-year periodbackdated to 2012 and had criticised management for seekingadditional concessions in exchange for more money.
"We want to get back to the negotiating table as quickly aspossible," Lufthansa board member Bettina Volkens said in astatement, adding she hoped the two sides could then discussother issues such as pensions.
A VC spokesman said the union could not immediately commenton the fresh proposal.
German businesses and some other Lufthansa staff have calledfor an end to the protests, which are costing the airline 10 to15 million euros a day.
The strike by pilots on Wednesday grounded almost 900Lufthansa flights and is the sixth day of strikes since lastweek. Lufthansa has cancelled about 4,500 flights since thewalkouts started last week, the latest in a series of proteststhat date back to early 2014.
Lufthansa says it has to cut costs to compete with leanerrivals such as Ryanair on short-haul routes and Emirates on longer flights.
One of Lufthansa's major corporate customers, Siemens, said the strikes were harming the Germany economyand the country's image and warned Lufthansa that it needed tobecome more reliable.
"As a major customer we have to consider how we can dealwith this on a long-term basis," Siemens CEO Joe Kaeser toldGerman daily Bild, adding that the pilots should resume talks.
Analysts have said the walkouts are a good opportunity forrivals such as Ryanair and easyJet to gainmarket share and could mean Lufthansa misses its 2016 profittarget. Its shares dropped 2.5 percent on Wednesday, also hit bya rising oil price.
The pilots' union Vereinigung Cockpit (VC) held a rally atFrankfurt airport on Wednesday morning, but also faced acounter-demonstration from Lufthansa ground crew, who feel thepilots are hurting the company and jeopardising jobs.
