Directorate General of Civil Aviation (DGCA) has said there are restrictions in place for Indian nationals desiring to travel to Germany which was putting Indian carriers at a significant disadvantage resulting in inequitable distribution of traffic in favour of Lufthansa.<br />''<br />'' India formalised an air bubble arrangement with Germany in July this year, which allows nationals of both countries to travel in either direction.<br />'' <br />''In a series of tweets, DGCA said yesterday that Lufthansa operated 20 flights a week as against Indian carriers operating 3 to 4 flights a week. In spite of this disparity, India offered to clear 7 flights a week for Lufthansa which was not accepted by them. DGCA said negotiations continue in the matter.<br />''<br />''<span style="color: #222222;">Lufthansa has cancelled all India flights from this date to 20th of October, citing 'rejection' of schedule by authorities.</span><br />
