Two more American airlines have joined United and Delta in banning the transport of hunting trophies.
US Airlines and American Airlines have now adopted the policy, prompted by online international outrage over the killing of Cecil the lion.
As well as lions the ban covers leopards, elephants, rhinos and buffalos.
Public pressure on the airlines grew when a Delta customer started petition online calling on the airline to stop shipping wildlife trophies. Around 400 000 people signed it.
