JAKARTA, Indonesia (AP) — The Indonesian mother of three had flown without her kids before, but this was the first time she gave her eldest a to-do list in case something happened on the flight she and her husband were taking. At airports across Asia and around the world, Flight 370 and its 239 passengers and crew, now lost for more than a month, are topics of avid speculation and sometimes anxiety. Passengers typically remain confident about the safety of air travel, but some are distressed by the disappearance, which — given the number of people involved — is unprecedented in aviation industry. "The mystery over the missing plane had created many confusing, even terrifying, theories every day," Yulveri said. Before she and her husband, an air force officer, left for a week-long tour of Japan's Hokkaido island, she talked to her 15-year-old daughter and asked her to take care of her younger siblings. Here's what air travelers across Asia said Wednesday, Thursday and Friday when they were asked, "One month later, how does the Flight 370 mystery affect your attitude toward flying?"
