When to book Las Vegas flights

Las Vegas tends to be a year-round destination due to the fact that you'll be spending most of your time indoors. However, if you do plan on going outside, the spring and the fall are the most pleasant seasons. Many people are under the impression that Las Vegas is hot throughout the entire year, but this is not true. Las Vegas can get brutally hot during the summer, but since the humidity is very low, the heat is surprisingly more tolerable than you would think. Many people don't realize that Las Vegas can also get very cold and windy during the winter. In addition to knowing what the weather will be like when booking your tickets, make sure to check out the convention calendar; Las Vegas hosts several major conventions every year, and if you want to avoid the crowds, try to stay out of Vegas during the conventions.

If you're looking to compare flights to Las Vegas, no travel company presents more choices than Expedia - more airlines, cheaper flights, fewer stops, and more departure and arrival times. Expedia provides the cheapest flights to Las Vegas and you may find even greater savings if you combine your flight to Las Vegas with a hotel stay.
