This is not a surprise.

First/second buyers of a new aircraft type most always are the proverbial guinea pigs who experience various aircraft snags.

Aeronautical history is full of examples; to wit the classic 747 experienced early snags.

This is frustrating for the airline who experience reliability and dispatch issues and aggravating to the travelling public who are inconvenienced by requent delays due to mechanical/avionics issues.

However..that too shall pass as the snags are worked out of the fleet.

It would however be refreshing if AC could take a page out of US Airways communication with frequent flyers and acknowledge the problem and tell people what to expect. After all, it is not a safety issue but one of reliability of dispatch.
