The Ottawa Airport is expected to have its busiest day of the year in the middle of a massive snowstorm.

Krista Kealey, Vice President of Communications and Public Affairs at the Ottawa International Airport Authority, told CTV they expect 8,000 people to fly into the Capital and another 8,000 to fly out as Christmas travel begins.

She says they will start de-icing planes early in the morning but people should expect delays.

Westjet and Air Canada have announced that they will waive re-booking fees to customers if they want to try to travel before the storm hits.

With between 20 and 35 centimetres of snow and freezing rain expected, a healthy dose of patience will be required.

In Michigan, the storm is already underway and residents are digging themselves out, giving Ottawa residents a preview of what is in store for them.
