The Old Rule: Why Returns Were King
Traditionally, legacy airlines built their pricing models around round-trip journeys. It offered them predictability, ensuring they filled seats on both legs of a trip. As a result, they incentivized this behaviour by offering a significant discount on a return
ticket compared to the cost of two separate one-way fares. A one-way ticket was often priced disproportionately high, sometimes costing almost as much as a full return journey. This model catered to travellers with fixed plans and punished those who needed flexibility, making the round-trip booking the undisputed champion for value-conscious flyers.
The Game Changer: Rise of Budget Airlines
The explosion of low-cost carriers (LCCs) completely upended this model. Budget airlines typically price their flights on a per-segment basis. This means a flight from Delhi to Mumbai costs what it costs, regardless of whether you’re planning to come back. For these airlines, a return trip is simply two one-way tickets bundled together, often with no inherent discount. This 'point-to-point' pricing strategy has forced even legacy carriers to become more competitive, leading to a market where the cheapest option is not always the most obvious one. This shift has empowered travellers to be more creative with their bookings.
When Separate One-Ways Win
There are several scenarios where booking two one-way tickets can lead to significant savings and greater flexibility. The most common is the ability to 'mix and match' airlines. For instance, IndiGo might have the cheapest flight for your departure, while Akasa Air offers a better deal for your return. A return booking with a single airline would miss this opportunity. This strategy is also perfect for 'open-jaw' trips, where you fly into one city and out of another. Furthermore, if your travel dates are flexible, you might find a cheap one-way fare on a Tuesday and a similarly cheap return on a Thursday with a different carrier, an option unavailable in a rigid round-trip search. It also allows you to use travel points for one leg of the journey and cash for the other, maximising your loyalty benefits.
Potential Pitfalls to Watch For
While the potential for savings is real, this strategy isn't without its risks. The biggest drawback involves flight disruptions. If you book with two different airlines and your outbound flight is cancelled, the second airline has no obligation to refund or rebook your return flight. You're left with a useless ticket. Similarly, making changes can be more expensive, as you may have to pay two separate change fees instead of one. For international travel, be particularly cautious. Many countries require proof of onward travel for entry, and immigration officials may view a one-way ticket with suspicion. Also, long-haul international flights on legacy carriers often remain cheaper as round-trip bookings.
How to Compare Fares Like a Pro
The only way to know for sure is to do the research. Always start by searching for your ideal trip as a standard return flight to establish a baseline price. Use a reliable flight comparison website for this. Once you have that price, perform two new searches for separate one-way tickets for your desired dates. Be sure to check the 'one-way' box in the search tool. Don't forget to experiment. Could you fly out on one budget airline and back on another? Check nearby airports and be flexible with your dates if possible. Finally, always calculate the 'all-in' price, including baggage fees and seat selection, as these can quickly erode the savings from a cheap base fare on a low-cost carrier.
