Air Canada's phone lines are so busy they can't even put people on hold

Frustration is growing as Canadian residents are worried about getting home following March Break.

Air Canada's customer service line is so busy right now, calls it can't even put people on hold.

People are trying to re-book flights after Canada joined dozens of countries in grounding the Boeing 7-37 Max 8 and 9 aircrafts because of safety concerns.

The aircrafts have been linked to two crashes in the past six months.

Passengers are being directed to Air Canada's website.
