"We are still forecasting a positive result of $8.9 billion this year," Giovanni Bisignani told Reuters Insider at an aviation security conference.
Two packages containing bombs -- both sent from Yemen and addressed to synagogues in Chicago -- were intercepted in Britain and Dubai last.
One of the packages was found on a United Parcel Servicecargo plane at East Midlands Airport in Britain. The other was discovered in a computer printer cartridge in a parcel at a FedEx facility in Dubai.
Bisignani at the conference warned against any hasty steps to implement new security measures and said governments need to collect all relevant facts first.
Responsibility for aviation security lies not only with airlines but also with other companies involved in the supply chain, such as freight forwarders, he said.
He called for cooperation between governments and all members of the supply chain to improve security. (Reuters)
