For the cheapest flights, try booking 1–3 months in advance for domestic trips and 2–6 months for international destinations. Keep an eye on our last minute flight deals section, especially if you're flying during off-peak travel seasons or midweek. 

Last-minute flights are usually more expensive, but last-minute deals do exist—especially when airlines need to fill empty seats. Look for flights midweek, use flexible dates, and monitor price drops 1–7 days before departure for potential savings. 

You can find cheap flights easily on SellOffVacations by using our flight search engine to compare prices from top airlines. Filter by flexible dates, sort by lowest fare, and explore featured flight deals for both domestic and international travel. We specialize in finding you the best flight deals all year round.
