I'm trying to understand.

back in the 70s, the 747 was toted to be this monster place to seat so many and have such a great interior, pianos, bars, etc.

throw in a gas crisis and they packed it with seats and that was that.

now the A 380 comes out in a similar fashion, similar climate and, well, how will it be "better"?

I mean. For example, lets say BA has 7 flights LHR-JFK a day. And assuming the planes used are mostly 747s with a 777 thrown in. Most of those flights, on a given day, are not full.

So why do we think a bigger a/c will do the difference? Arent we just looking at more empty seats?
