European Union and US negotiators reached a deal on the sharing of trans-Atlantic air passenger data used in anti-terror investigations, diplomats said Friday. Details of the exact deal were not yet clear after marathon talks which started late Thursday. Reaching a new deal had been an EU priority to ensure airlines can continue to legally submit 34 pieces of data about passengers flying from Europe to US destinations. Such data - including passengers' names, addresses and credit card details - must be transferred to US authorities within 15 minutes of a flight's departure for the United States. Washington had warned that airlines failing to share passenger data faced fines of up to US$6,000 (€4,700) per passenger and the loss of landing rights.
