Re: This underlines one more thing
The issue is that the A380 (and B747) weren't economic in the era of the wide bodied long range twin motor.
Incorrect. Singapore Airlines has just taken delivery of new A380 bodies to replace the ones that went off-lease. The reason why MSN003 and their contemporaries are being retired is because they are fat. They are the first of their kind... some things hadn't been ironed out yet. Later bodies were better, the processes had smoothed out, weight was shaved off. Why should someone like SQ fly with jets that are older, more tired, need more TLC when new jets are literally there for use.
And the A380 *is* economic. It is always full between LHR and SIN and FRA and SIN. You cannot for the life of you get reward tickets in business or first. Emirates makes the A380 run pretty full every single flight. It's the 17 hour flights that need smaller jets that can do longer distances. The new SQ flight between SIN and EWR (Newark) will be *all* Premium Economy and Business. There won't be economy on that flight.
