Obviously MIL was once a profitable route for CP for many years as were other destinations such as AMS, Rome, Ham??, etc. which is one of the reasons why AC bought CP--toget these routes. I cannot imagine the demand has gone down that much in the last 6 years esp with AC dropping so many other European destinations. Esp with population growth and globalization.
Of course some of these routes have been picked up by new *A carriers out of their hubs but still one has to wonder.
AC's map in Europe is now down to a mere fraction of what it once was...only LHR, CDG, FRA and MUC (but for how much longer?). Gone are so many other long time destinations such as MIL, FCO (although it is coming back soon but is this only seasonal?), AMS, Zurich, Glasglow, MAN, MAD, Dublin, Berlin, Nice, etc.
The list of now defunct destinations is longer than the list of existing destinations. I too hope AC can muster some new business on new European routes.
