I'm sure everyone have monopolised certain routes before, but did anyone manage to monopolise an entire country?

The R5 game that I've just completed, I've successfully monopolized the entire continent of Australia as well as New Zealand. There were 0 competitors for 75% of the 30 year game length. Basically I had the control of all domestic routes within Australia and only met fair competitions with routes to Asia and North America. Typically Australia is a small market but when there's no one around, it is easy to obtain $500M DOP with 1600+ routes and 2500+ aircrafts.

Since one game takes about at least 3 month and sometimes can last up to 9 month, and there are hundreds and thousands of competitors, so finishing with an award is pretty much as difficult as passing a school term/year while being the top 1%. So how would you congradulate yourself? Especially for first time winners.

Competition is too strong and just not enough time to care

7 aircrafts and 24 on order, 25M valuation, ranks 130 on average
