You can also book with separate airlines for your outbound and return journeys, from $266 one-way. Expedia also offers Price Drop Protection, so if the cost of your airfare goes down after booking, you'll receive a credit for the difference\*. This is available for a small fee, and is free to One Key Gold and Platinum tier members. Expedia's Price Tracking feature means you can stay on top of airfares without manually checking every day. It sends you automated price alerts for cheap Ontario to Nice flights and uses historical data to indicate when the best time to book is. Download Expedia's free app to activate this handy tool in a few easy taps. You could also save big by booking one of Expedia's [vacation packages](https://www.expedia.com/package-deals). Bundling together your Ontario to Nice airfare with your accommodations and car rental is often cheaper than booking everything separately. There’s also One Key, Expedia's generous rewards program. Join for free and you could earn One Key cash on most bookings to save on future adventures. \*Terms apply.
