A340-300 Vs 777-200ER?

A340-300 burns 5% less fuel than 777-200ER: Airbus

Airbus COO John Leahy noted that compared to a Boeing 777-200ER, the A340-300 burns 5% less fuel, with a few less seats this means it has equal fuel burn per seat (aviationnews-online.com, 04-Dec-2013). He also stated the maintenance cost on four engines is less than the maintenance cost on two engines for the 777. While Mr Leahy conceded that the A340-600 burns more fuel than the GE90, he noted that fuel burn is lower than the 747-400, adding that the engine maintenance costs are the same thanks to Rolls-Royce's four for two price promise (it has committed to a four engine maintenance cost that is equal to the maintenance cost of two) and the airframe maintenance costs are also equal. He also noted that the A340 is available short-term as a replacement of other ageing aircraft as well as providing interim lift before the A350 XWB becomes available. He said that aircraft type is also ideal for charter/niche operators with high capacity requirements as well as long-haul start-ups

Se le olvido al Sr. Que ya no se produce mas ese avion? Hehehe

Entiendo quieren darle un empujón al mercado del A340 de segundo cachete

Pienso que tener dos motores mas son dos posibilidades mas de que alguno falle.. Dos posibilidades mas de comprar refacciones.. 50% mas de aceite y/o algún liquido que haga mover las turbinas..

Por algo el 350 tiene dos motores..

Fer, concedido, pero en rutas de largo alcanze y en lugares remotos, esos dos motores extras significan que si uno falla, puedes continuar a destino sin ningun problema.
