ABU DHABI, United Arab Emirates (AP) — The director of the International Air Transport Association said Monday he wants to see a globally agreed upon tracking standard in place by the end of this year, which also takes into consideration the cost on airlines, in order to avoid another disappearance like that of Malaysia Airlines Flight 370.

Tony Tyler told a small media gathering in Abu Dhabi at the Global Aerospace Summit that the cost of tracking will have to be examined in any decision. He said profit margins for the global industry this year are still very narrow and expected to be around $5.65 per passenger.
