What is IIRC? I understand the 3-4-3 is the seating arrangement and what is A/C? What is replacing the 747?
Thank you very much!
The 777 holds nearly the same number of people, but needs only 2 engines (greatly reduced maintenance costs), The engines are probably more efficient, too, so there is fuel savings.
The A380 was mentioned in another post, but that is on the way out, too. COVID seems to be accelerating the phase-out.
The 787 isn't a direct replacement for the 747, having about 100 fewer seats than the 777. It's intended for "Long, thin" routes, which are long distance flights with fewer passengers than a 747 or 777 would justify. This allows direct routes to many destinations with fewer, or no, intermediate stops. It displaces a 747 or A380 by bypassing some of the international hubs. For example, direct flights from Denver to Frankfurt, London, or Heathrow are feasible now. Prior to the 787, passengers would go from Denver to San Francisco or Chicago and take a jumbo to those places. Denver otherwise doesn't have the population to support direct jumbo flights.
