國泰擬購「空中長氣袋」

佢叫得boeing出777既計劃書就知應該吾再堅持了

不過我想問呢...
777-200LR同埋777-300ER，除o左長度上分別之外，仲會有邊幾處(performance上)
o既明顯分別呢？

因為一時講772LR，一時講773ER...而睇返波音o既網頁，772LR比773ER飛得更遠，
咁係唔係應該772LR多過773ER呢？

PS: 小弟只不過係新手...歡迎指教

咁其實CX係唔係買772LR好過773ER呢？始終772LR o既「可用性」同埋running cost
理應比773ER更好...

CX諗773ER多過772LR，會唔會係因為成本甚至係交貨時間問題呢？

PS:唔會有773ER之餘，亦有772LR掛... 咁CX o既B777系列都幾豐富喎~

相信同載客量有關，國泰一向鐘意買大機，大約350-450 之間，可能 B772LR 載得少人D，而 B773ER 相對 B744 差唔係太多... 所以考慮 B773ER 多D...

P.S. 其實 B772LR，CX 可以考慮飛南美洲或二級美國東岸、歐洲城市...

我估係因為CX用開773﹐可能其成本效益同埋個Requirement係符合CX本身既要求﹐that's y CX先會consider 773ER先呢........

無獨有偶，QF都搵新機中...
