However, you'll still be able to find a flight to Singapore with at least one stop. ### Are Ottawa International Airport to SIN flight tickets cheaper when they're purchased at the last minute? > It is possible to pick up a great last-minute deal from YOW to Changi Airport (SIN), but it can also be hit-or-miss. As many airlines release seats up to a year in advance, it's worth keeping an eye on fares early and being ready to pounce when you see a good bargain. Expedia compares carrier prices and updates flight deals often, so you can rest easy knowing you're always seeing the latest offers. ## Explore a world of travel with Expedia - Lodging - Flights - Packages -
