I have never flown AC's 340-500. But, it is my understanding that only having 2 planes on this dedicated route for AC has caused both passengers and airline exterme grief with maintenance delays having no substitute aircraft available.
Search in the AC forum...it seems to happen with a relatively high frequency...
