According to justplanes.com...
India will give Lufthansa an additional 7 flight slots by 2003 in exchange for royalty payments to Air India.
Lufthansa will be allowed to add slots as follows :
2 new flights in summer 2001
2 new flights in summer 2002
3 new flights in summer 2003
Lufthansa will likely use the first 2 slots this year for A340 service from Frankfurt to Bangalore.
BTW, will LH fly to Chennai as well?
