Also the ticket system in AWS seems to be Y class oriented, every airline is DL/KL/CO/AF/BA even CA/CZ/MU and CX/SQ/JL/NH/KE are all airlines from Mars. And lack of competition over on board service make the usual way of "service+hardware improvement--> increase price" almost not possible in AWS. CX can still make big money with only 297 seats (F6J53Y238) on 77W, and in AWS you will get killed by this.
Thats because on airlines like BA, Singapore, Emirates, CX, Qantas, Qatar, Korean and all the other heavy premium airlines 60-80% of the revenues come from the smallest cabin spaces of first and business (thats a quoted percentage from insiders). Thats why when the GFC hit, BA and a lot of the Asian airlines took major hits and went from being profitable to loosing tons of money and some having to greatly reduce capacity.
as for the 777, that must ahve been why my first airline bk-ed. i introduced it to my all a320 fleet and instantly stopped growing. then when all the A320's disappeared from the market, in a last ditch effort, i used 727's which caused me to bk. i dont really know why when i have seen others use them to great success and my competitor was using them as part of his other 9 family fleet that consisted of 60 a/c... must have been all his intl flights providing the profits
Generally speaking, the A330 and A340's are lighter than their respective 777 variants which means they are going to burn less fuel (yes a 777W burns more fuel than a 340-600), however the 777 can lift considerably more payload and take it further than the 330/340's. This is still even the case with the 777 vs A350, hence the reason why Airbus is now trying to change the 350-1000 to match the 77W. Passenger wise, they are relatively the same, but the increase in payload for the 777 comes in the belly. The 777 actually carries the most belly cargo of any passenger airliner. Without having cargo, that is where the disavantage comes for a lot of the planes that underperform in this game. I personally think, cargo should be a top priority. like type said, cargo makes more money for an airline than passengers do.
