Input: The recent killing of a popular lion named Cecil by an American dentist in Zimbabwe sparked considerable outrage on social media and elsewhere against safari hunting. The event has also brought to light the role that airlines play in transporting trophy kills as cargo, and may have contributed to changing airline policy. 
  
 On Monday, Delta Air Lines became the latest carrier to change its rules about transporting hunting trophies. Its announcement came as a group of airlines including Air France, KLM, Iberia, IAG Cargo, Singapore Airlines and Qantas signaled last week they would ban the transport of trophy-hunting kills, according to Paul Ferris, the campaign director at SumOfUs.org, a consumer-based petition agency in Brooklyn, which has pressed for changing cargo policies. 
  
 “Airlines and other large travel corporations would be foolish to ignore the public reaction to the killing of Cecil the lion, and growing concern about the plight of endangered species,” Mr. Ferris said. 
  
 Such a ban was initiated by South African Airways in April, and Emirates, Lufthansa and British Airways later joined. These airlines pledged not to carry big game trophies, including elephants, rhinos, lions and tigers as cargo. ||||| Delta issued the following statement today: 
  
 Effective immediately, Delta will officially ban shipment of all lion, leopard, elephant, rhinoceros and buffalo trophies worldwide as freight. Prior to this ban, Delta's strict acceptance policy called for absolute compliance with all government regulations regarding protected species. Delta will also review acceptance policies of other hunting trophies with appropriate government agencies and other organizations supporting legal shipments. |||||
Output:
More fallout from the killing of Cecil the lion: Two major American airlines say people whose hobby is killing and beheading African wildlife will have to fly other carriers if they want to take the animal parts home with them. In a statement, Delta Air Lines said it has now banned "shipment of all lion, leopard, elephant, rhinoceros, and buffalo trophies worldwide as freight" and will review its policy on other hunting trophies. Other airlines, including KLM, Air France, and British Airways had already implemented or announced an end to the carrying of hunting trophies as cargo but Delta, which has direct flights to numerous African cities, had been a major holdout, the New York Times reports. Online petitions have targeted carriers still accepting big-game trophies and last night, American Airlines tweeted that it too will cease to transport lion, leopard, elephant, rhinoceros, and buffalo trophies, the BBC reports.
