The number of passengers travelling through Christchurch airport is set to soar

From today, planes and passenger numbers at the airport will ramp up to what will be a busy school holiday period for travellers.

On the busiest days, the airport is forecast to see up to 20-thousand people on regional, jet and international flights.

Chief Aeronautical and Commercial Officer Justin Watson says the three Fridays of the July school holidays - July 8, 15 and 22 - will be especially busy.

He says it's great to see schedules reaching pre-Covid numbers.
