Re: Rumor: Airbus to launch A350-1000ULR

Perhaps Singapore is also seeing the benefits of going to 10-abreast on the 777-300ER as Cathay has (?), yet would prefer to just go direct to the 777-9 with a common seat as their A330-300, A350-900 and A380-800 fleets. And of course, there is nothing preventing Singapore from eventually adding th...

Re: A320neo vs B737max

The 737 MAX 8 weighs about the same as the A320neo but carries more passengers. That's how it remains competitive, at least for some mission profiles.

Re: Why was there an innovation drought during the 1990's and 2000's?

The 1990s and the 2000s saw massive advances in ETOPs and performance of jet engines, which led to twin-engined widebodies dominating the market for widebody airliners and started the decline of quads.

That's a game-changing innovation.
