Traveling around Christmas can be a little tricky when it comes to finding the cheapest flights. Airlines typically increase their fares around the holidays due to increased demand. However, if you're willing to be flexible with your travel dates and destinations, you can find some great deals on flights. The best time to find the cheapest flights is typically during the shoulder season, which is the period between the peak summer travel season and the winter holiday season. This is when airlines offer the best deals to encourage people to travel.
