A widebody aircraft requires a very large support network. It's not enough to look at other carriers and say "they come here with widebodies everyday. We should get our own and we'll fill ours too." People travel on bigger carriers for their route network which sadly, Air Tanzania does not yet have. It would be great to see the airline grow and open up opportunities in the region. However, growth should be cautious lest they realise that a widebody can sink a company into debt levels equal to the GDP of a small country.
