A 10-year, $1.8-billion upgrade announced Wednesday for Vancouver International Airport will see passengers travelling to destinations outside of B.C. facing a $5 increase in the airport improvement fee to $20.

However, the Vancouver Airport Authority, the not-for-profit group that runs the airport, says the fee will still be among the lowest in Canada, with most other major airports collecting $25 per passenger.

Passengers travelling within B.C. and to the Yukon will continue to pay just a $5 fee, the authority said in a release. The increase takes effect in May.

The last increase in the airport improvement fee was in 2004. Although at one time the fee was collected directly from passengers, it now is added to ticket prices at the time of purchase.
