Flights across the U.S. are currently available for under $100, and if you still have vacation days remaining, you're in luck because many of these low fares are available before the year ends.

There are various routes available, so don't get bummed if you don't see your city in the list of examples. Head to Google Flights, plug in your departing city, put in "United States" as your destination, bring the price scale down to $100 and see what destinations are available from your city.

Note that all of these fares are non-refundable and can't be changed. Additionally, you will have to pay extra for carry-on and checked baggage. However, if you're just going for a quick trip then a personal bag shouldn't be too much of an inconvenience.

Finally, click through to book directly with the airline or through an OTA like Priceline or Expedia.
