These were the reasons for sacking, as outlined in the Hong Kong Mail.
"Director of corporate development Tony Tyler told a press conference last night that the sacking of the three pilots had been "in accordance with their conditions of service and the Hong Kong Employment Ordinance''.
He said one of the pilots was an eight-year veteran and union member who had received a previous warning about his job performance and was terminated after flight CX889 arrived from Vancouver two hours 10 minutes late on Tuesday.
The second pilot, who was not a union member, was fired for not taking enough rest before showing up to fly - a serious breach according to Mr Tyler.
The third pilot, a union member with 11 years' employment was sacked after he failed to report for duty without a "satisfactory reason'' for CX883 from Los Angeles.
Mr Tyler said the firings were "related to the particular actions of particular individuals'' and insisted there was no retaliation over the industrial action that began on Tuesday."
