If BA, Cathay or Qantas could swap those RR powered 744s for GE powered 744s they would do it in a second. There is a reason why RR powered 747s and 767s are valued between 20% and 30% less than the GE powered.
Did I hear someone say "mistake" and "777" in the same sentance? One can only say those two words in a sentence that also includes the A340.
I.E. Singapore mistakenly bought A340s and traded them for 777s would be more appropriate.
