Flights can make a national itinerary possible, but airport time and schedule risk still need to be counted.
Choose gateways by region
Vancouver, Calgary, Toronto, Montreal, Ottawa and Halifax serve different regional plans. A cheaper airport may add expensive ground transport.
Allow connection margin
Winter storms, summer thunderstorms, wildfire smoke and remote-airport schedules can affect connections.
Check baggage and equipment
Outdoor gear, child equipment and regional aircraft may have special limits.
Remote flights
Northern and fly-in communities can have limited frequencies and high fares. Weather buffers are essential.
