CATHAY Pacific Airways will install in-flight televisions in all classes and telephones and fax machines on every aircraft in a $1 billion upgrading over the next three years. The airline said plans included increasing business class leg-room on long-haul Boeing 747-400 flights by 50 per cent, which meant cutting back 11 seats from each jumbo. The number of flight attendants per aircraft would be increased from 17 to 18 on 747-400 routes and from 11 to 12 on Airbus Industrie A340 routes. About 150 new flight attendants would be employed. Deputy commercial managing director Simon Heale said the $1 billion would come from internal funds and there were no plans to increase air fares. 'We are hopeful our present revenue growth rates can be sustained,' he said. 'We believe we can absorb these costs.'
