When it comes to yield (which would not cover the above presumption, but we'll take it as this covers the profit and you know I like profit!!) I have to rely on what the station managers say (off the record naturally), that is the 380 only generates profits if almost full and with full fare premium passengers.
Aah yes the station managers with their degrees in economics, yield management and possibly marketing.
These would be the same station managers that sing Airbus praises and bemoan the Boeing crews to us when we are there and 3 hours later sing Boeing praises and bemoan the Airbus crew when you guys are there.
Look up the word gullibility, and while your at it, on your next flight, ask your most junior Grade 2 which aircraft she thinks is better. I've got a pretty good idea what her answer will be. I know what her answer will be when I ask here the same question on my flight.
