Air France KLM, Europe's largest carrier, is aiming for synergy savings of €465m in the current 2006-2007 financial year.
The target figure compares with the €350m savings made since the two carriers merged in 2004.
The carriers said the synergies so far had "exceeded our targets."
Mr Paul Gregorowitsch, KLM's executive vp commercial, told a press briefing in London that in the first year of the merger, the new grouping had hoped to save €27m in synergies in commercial fields in the international market.
They had in the end achieved €34.3m in savings.
This current year, the group was aiming for savings in these international markets of €61m.
Mr Patrick Alexandre, Air France's executive vp international commercial, said the two airlines had now signed more than 2000 joint corporate contracts world which enable customers to fly out on one airline and back on the other.
The only places where there were single contracts were to destinations served by only one of the carriers.
He said corporate business remained a priority and Air France KLM worked closely with travel management companies like American Express, Carlson Wagonlit Travel and BCD Travel.
Mr Gregorowitsch said: "It is quite unique what Air France and KLM are doing. It is not like a jig-saw puzzle where you copy the picture on the box. It is more like Scrabble where there is nothing to copy.
"We keep finding new synergies and we are bringing results to our customers, our employees and to the financial markets, despite the high fuel prices."
The briefing was held to mark the inauguration of the new joint offices in London near Heathrow Airport. The building will house 180 staff.
Mr Gregorowitsch said the airlines were rationalising staff, including bringing together sales teams.
There were now 11 station managers who supervised staff from both airlines. Since April six regions were being jointly managed, among them Scandinavia and the Baltic and Belgium and Luxembourg.
In the coming year this would be extended to six more stations, among them Athens, Geneva and Warsaw.
Mr Alexandre said two managers would only be retained where it made sense to do so, like London.
