Scubes!
I think you made the right decision. I have been with KA for a few years now and it is just getting out of control. No one can tell you what is going to happen to the 747s. Actually their 3 year plan that they presented last year was shorter than this post...No aircrafts on order either.
I can to 90 percent say that you are better of in BA. If you check with our guys in EU they will tell you that they sometimes have to pick up flights out of AMS and other places...on their own cost. (Keep in mind that it is sometimes easier for the guys as it might be closer to home.)
Out GMO is now trying to get a deal with DPA on this. If this happens you would ending up commuting on your own cost in EU.
Anyway I am pretty sure you did the right thing!
