I just hope that TNT retain at least two A300's , even if only one route, (LGG - EMA - BFS), is earmarked for their exclusive use. Retaining only one of anything spells disaster. The TNT A300's are remarkably well maintained, but can still fall over on a regular basis, (as well as, admittedly, not even induce a minor defect for a whole fortnight!). Nobody has A300F's to lend "locally", and transfer of the load on to another a/c type always causes havoc and DELAY. The route in question was always "ring-fenced" where allocating a/c was concerned, as it was always deemed important that it ran, and with no DELAY.
There you are, just taught a whole class of grandmas to suck eggs. The coal-face and their immediate bosses know their jobs really well, but that's not to say the higher, more remote echelons of TNT do not need reminding of my opening gambit. Stranger, more illogical things have happened there, believe you me!
