Is the new rule of airlines sharing passenger data with customs a violation of privacy? PNR locator, reservation date, travel date, frequent flyer details, issue of free tickets, upgrades, contact info, billing info, credit card number, travel agency - there's a new mandate and all this data is being given when you depart India or arrive in the country. The justification for all this - the broad sweep of 'national security'. Is this an invasion of our privacy?
