B-HNL is actually the very first 777 and was delivered to CX very recently after refitting and re-engining. Cathay's first 777 was B(then VR-)HNC, delivered in May 1996. ('HNA wasn't delivered until August of that year. It was actually the first Trent powered 777 and thus was involved in flight testing.)
Incidentally, anyone know a timeframe for refitting the first four 777s to -300 standard, eg PTVs etc.?
