Congratulations on your appointment! With the extra aircraft coming, the chances of a 100% contract looks good. Hope it works out for you and everyone else too.
Yes, an identical model would be the ideal situation but the B767-328(ER) is a rare bird. Only AF ordered them and only 6. They took 3 and did not take up 2, which went to Royal Brunei. The sixth one was never built and may never be built. As far as I can see there is only one about that may be available and VARIG doezn't have it.
