Low cost carrier Air Berlin has increased its German domestic market share to 25% after efforts to enhance its business-leisure model.
The airline's corporate travel share of 20% strengthened after acquiring DBA, Titus Johnson, Air Berlin's UK and Ireland manager, said.
Mr Johnson also hinted that with oil prices falling, Air Berlin routes to Beijing and Shanghai "may be" back on the cards.
Air Berlin has improved its standing in the leisure market after buying charter airline LTU and increasing its fleet to 140 aircraft serving 29m passengers a year.
However, the airline has recently experienced difficulties. Plans to buy TUI's leisure carrier, TUIfly, are reported to have been suspended earlier this month.
According to another report, Air Berlin's share price plunged this month, valuing the airline at €190m, an 80 percent loss in market capitalisation.
While unable to confirm or deny any expansion plans, Mr Johnson said next year will be a "very interesting" one for the airline.
The business class product has been improved with additional services, separating it from ‘no-frills' airlines such as easyJet and Ryanair.
As reported on ABTN last month Stephan Nagel, senior vice president strategy for Air Berlin, stressed the use of a GDS in the airline's "hybrid" business-leisure model.
Mr Johnson said: "The use of the GDS is important. We're making Air Berlin more attractive to corporate customers and TMCs as we don't charge for these services.
"We're the only low cost airline without surcharges."
Air Berlin also offers a frequent flyer programme for business customers, distancing it even further from the no-frills airlines.
Mr Johnson confirmed that an order for 50 Boeing 787 ‘Dreamliners' is going ahead despite recent aviation industry difficulties.
The new 787s, due in 2013, will mainly serve leisure destinations, however they will feature flat bed seats in business class.
Air Berlin is the third most punctual airline, having increasing its on-time departure rate to 80%, topped only by larger network carriers.
