Maybe fly home from a different city and save money?
I use this strategy to check if it is cheaper to book two one-way trips instead of a round trip every time I book a flight. It works!!
Example:
You’re flying from Phoenix to Dallas.
(Keep in mind Dallas has two airports to save even more money).
Check the one-way flights each way instead of round trip. Maybe you want to visit Austin or San Antonio and fly home from there?
This theory also allows you to take advantage of using different airlines each way too as round-trip travel booking normally uses the same airline.
Keep in mind some airlines have better baggage rules too which may also change the overall cost of your flight. Greedy bastards!
The below article from Clark Howard clearly explains a few other reasons too! 
Booking air travel can be tricky these days. The airline industry continues to push fares higher and higher while passengers look for ways to keep them grounded.
Money expert Clark Howard says if you’re flying domestic (this doesn’t necessarily apply for international flights), a new strategy for airline customers to save big for 2025 is to avoid the traditional practice of shopping for round-trip itineraries.
One-way flights often offer a cheaper opportunity to fly to where you need to go, Clark says.
And it all starts with the click of a button: When you visit a search site like Google Flights or Kayak and you choose one airline in the search results, it will automatically show you the return flights for that airline as well.
“But often the fare may be cheapest one way on American or cheapest the other way on Southwest. Or maybe cheapest on United one way and JetBlue the other, and on and on and on,”
Here are two reasons why shopping for one-way flights is now the way to go:
Reason #1: Airlines Are Hiding Their Best Domestic Fares on One-Way Itineraries
“When you buy a fare one way or shop one way, you’re going to see lower prices than if you look roundtrip,” Clark says. Of course, this might not always be the case every single time due to seasonal sales and whatnot, but the point is that you should be checking one-way fares just as you would normally check round trips.
You don’t have to be a tech whiz to research the latest fares online, but it pays, especially in this current airline environment, to have a basic understanding of how to search for cheap fares on the web.
“This doesn’t necessarily apply outside the United States, because a lot of fares outside the U.S. are set where round-trip tickets are cheaper than two one ways,” Clark says. “In Europe, sometimes it is cheaper, but I digress on that.”
So, searching for one-way plane tickets is how you help your wallet. Our guide on how to save money on Google Flights is a great place to start.
Reason #2: Flight Modifications Could Now Cost You Big
Another reason why you might want to check out one-way fares is that there’s a new refund rule that airlines have interpreted to the disadvantage of passengers, Clark says.
The U.S. Department of Transportation’s recently enacted law that forces airlines to refund passengers pronto for significantly changed or canceled flights has resulted in an unforeseen consequence for deal-savvy customers.
“If an airline has a big schedule change on one of your flights, the airline will refund your whole ticket and say, ‘We’re sorry, we had this big schedule change.’ You’ve got to start over,” Clark says. “So what happens when they do that and you had a great fare? You’ve now lost it,”
Looking for the Best Deal? Search Different Airlines
Not only do you want to shop for one-way tickets arriving to and departing from your destination but you want to look at several different airlines.
“When you shop, it’s going to take you a little bit longer, but the savings can be enormous if you’re a free agent,” Clark says. “If you’re not captive to one particular airline [and] you’re looking for the best deals, you’ll want to do your fares one way.”
Although budget airlines typically showed the cheapest flights, I saw fares from other airlines as well, along with the type of aircraft, which is another Google Flights feature that can help determine your choice.
