From the Washington Post, the sequentially issued tickets to the two individuals with the stolen passports were sold by a travel agent in Pattaya Thailand. No information on routing from Bangkok to Kuala Lumpur. Subsequent itinerary was Kuala Lumpur to Beijing to Amsterdam. At Amsterdam, one individual booked to Copenhagen, the other to Frankfurt. Seems like a circuitous routing to their final destination.
Would not immigration officials at Schiphol receive a passenger manifest of the incoming flight, and check that manifest against a database of reported passport losses, and identify that individual for special attention on entry?
