Yes looks like it is the DGCA intentionally restricting as many Canada bound passengers as they can through such clauses for other airlines, for the straight benefit of VBM (because Air India is allowing COPR's).... Very sad and frustrating ..maybe they have a round of India-Canada flights coming up on Air India..and they want to use the piled up demand for that ..who knowsI think these criteria are established based upon the approval given to these Airline by DGCA. Lufthansa has stated it specifically.
As per the approval given to Lufthansa by the Director General of Civil Aviation, only the following persons shall be allowed to travel on the special repatriation fights......
