Osaka Budget Airlines | Ultimate Guide to Cheap Flights
Low-cost carrier (LCC) routes between Taiwan and Japan have expanded rapidly in recent years. Special deals and promotions pop up online constantly, offering travelers more flexible and affordable flight options than ever before.
In this post, I have put together a comprehensive breakdown comparing Taiwan–Osaka budget airlines, tips on scoring the cheapest airfares, and my actual boarding review. I hope this helps you plan an amazing Kansai getaway!
1. What Is a Low-Cost Carrier (LCC)?
A Low-Cost Carrier (LCC), commonly called a budget airline, achieves significant operating cost reductions by stripping out optional complimentary add-ons, selling tickets directly online, utilizing single-class cabins, and charging for onboard amenities on an à la carte basis. In simple terms:
- LCCs provide essential transportation only; add-ons like meals, checked baggage, and seat selection cost extra.
- They often operate streamlined fleets of modern, fuel-efficient aircraft, frequently use budget terminals, and can have less conventional flight schedules.
- For travelers with flexible schedules and minimal service demands, they are without a doubt the most budget-friendly way to fly.
2. Which Budget Airlines Fly to Osaka?
Currently, there are 5 budget airlines operating direct routes between Taiwan and Osaka (Kansai International Airport):
| Airline | Tigerair Taiwan | Peach Aviation | Jetstar Japan | AirAsia | VietJet Air |
| Flights from Taoyuan (TPE) | 2 daily | 2 daily | 2 daily | 1 daily | 1 daily |
| TPE Departure Time | 06:40 / 15:15 | 09:30 / 18:45 | 02:30 / 18:20 | 15:40 | 07:45 |
| KIX to TPE Return | 11:15 / 19:50* | 07:50 / 15:45 | 15:25 / 23:35 | 21:05 | 12:25 |
| Flights from Kaohsiung (KHH) | 1 daily | 1 daily | - | - | - |
| KHH Departure Time | 06:55* | 14:50 | - | - | - |

| Notes | ※ All prices are in New Taiwan Dollars (NTD). VietJet fees are converted from VND and fluctuate with exchange rates. Comparison is based on each carrier's basic fare class. ※ Tigerair Taiwan departure times may vary by 5–10 minutes depending on the flight date. LCC fees change frequently; please refer to the official websites for real-time pricing. |

In terms of flight frequency, schedule convenience, and user reviews, I personally recommend Tigerair Taiwan and Peach Aviation. Both serve both Taoyuan and Kaohsiung with very decent flight times (especially Peach). Both also run frequent sales with great bargain fares.
3. How to Find Cheap Osaka Flights?
Next, let me share the two major flight search engines I introduced in my Okinawa Budget Flights guide: Skyscanner and FunTime. These tools not only aggregate all possible budget flight combinations but also let you compare fares instantly to lock in the lowest price. I rely on both heavily whenever I travel!
1. Skyscanner
Skyscanner is the world's largest flight comparison platform and the default choice for global travelers. Beyond comparing direct carrier prices across budget and legacy airlines, it also tracks hundreds of third-party travel agencies (OTAs). Checking Skyscanner before booking Osaka flights is essential!
(What I love about flight metasearch engines is that they display tax-inclusive final prices. Some budget carriers only show pre-tax base fares during search and booking steps, tacking on airport taxes only at final checkout. Using comparison platforms eliminates nasty surprises.)
(Skyscanner also features an intuitive calendar and bar chart view showing which dates offer the absolute lowest rates—a lifesaver if your travel dates are flexible. You can also easily switch language and currency in the top right corner.)
2. FunTime
Similar to Skyscanner, FunTime is a flight metasearch engine with a dedicated budget airline tab, making it exceptionally user-friendly for budget travelers. Because it caters primarily to Taiwan-based travelers, its greatest strength is aggregating deals from Taiwanese local agencies and third-party sites that Skyscanner often misses. Comparing multiple tools ensures you never miss a deal!
(FunTime features a Real-Time Budget Airline Deals Hub. This tool is brilliant—it gathers active airline flash sales in one place so you don't have to monitor each carrier individually, counts down promo deadlines, and even previews upcoming sales so you know exactly when to pounce.)
(Just like Skyscanner, simply select your departure and destination to see all budget airline route combinations with zero full-service clutter, perfect for travelers strictly seeking budget deals.)
(The "Low Fare Calendar" on FunTime highlights prices across neighboring dates on your chosen route, making it effortless to pinpoint the cheapest flight days if you have date flexibility.)
Generally speaking, Osaka flights go on sale quite frequently. Base one-way fares often sit between NT$2,000 and NT$2,500 (pre-tax). As a rule of thumb, a Taiwan–Osaka round-trip ticket without baggage priced under NT$6,000 (tax inclusive) is a decent deal, NT$5,500–6,000 is an excellent buying window, and securing anything under NT$5,500 round-trip with taxes is an absolute steal!
4. My Experience Flying Budget Airlines to Osaka
I have flown to Osaka twice on budget airlines, both times with Peach Aviation during promotional sales. One unique quirk about Peach is that flights originating in Japan are priced in Japanese Yen (JPY), meaning buying two one-way tickets can sometimes be cheaper than a round-trip ticket (depending on JPY exchange rates or foreign currency credit cards, though booking requires an extra step). For our trip, we booked outbound and return legs separately.
On our most recent trip, three of us traveled together. Two booked the outbound flight first, a third friend joined last-minute and booked later, and then all three of us booked the return leg together. We purchased and shared one 20 kg checked bag for both legs:
- Outbound total: NT$8,710 incl. tax (NT$2,903 per person)
- Return total: ¥31,760 incl. tax (approx. NT$8,000 at the time; NT$2,666 per person)
- Final round-trip cost per person: roughly NT$5,569!
(The outbound cost comprised two tickets totaling NT$5,860 plus one ticket at NT$2,850, summing to NT$8,710. The price discrepancy happened because LCC promo seats are capped; once a discounted fare tier sells out, pricing moves up to the next tier, which is why acting fast during promotions is key.)
(If booking separately feels like a hassle, booking round-trip directly on the Taiwan site works fine. We only split it because we held yen-denominated credit cards and had exchanged cheap JPY earlier. Keep in mind that we split one 20 kg bag among three people; extra bags, seat selection, and in-flight meals will add to the total, as that is standard for the budget airline model.)
(I departed from Taoyuan Airport. Compared to early-bird flights on other LCCs, Peach's morning departure is actually quite reasonable—you get decent sleep the night before and land with a full day of sightseeing ahead. Many LCC flight slots have significantly improved in recent years.)
(I have taken budget airlines to Japan multiple times, including trips to Okinawa, Osaka, and Tokyo, mostly with Tigerair, but Peach for both Osaka trips. While seat pitch on both carriers is definitely snug, that comes with the low-cost territory. Considering how much money it saves on short-haul flights, it remains my top go-to option.)
(We finally arrived at Kansai International Airport (KIX)! Most budget airlines arrive at Terminal 1, while Peach uses Terminal 2, so you will need to take the free shuttle bus to Terminal 1 to connect to JR lines or Nankai Electric Railway into Osaka and Kyoto.)
(Located right next to Terminal 1, Kansai-Airport Station is where you can pick up handy transport passes, such as the Kansai Airport Express HARUKA Discount Ticket and Nankai Rapi:t Airport Express tickets. For transit pass breakdowns, check out my Osaka Transportation guide.)
(If you are planning a road trip around Kansai, car rental counters are situated on the 1st floor of the AEROPLAZA building next to the station. Booking in advance is highly recommended; see my Osaka Car Rental guide for tips.)
That wraps up my guide to Osaka budget airlines! Low-cost carriers are an unbeatable way to slash travel expenses. Both budget and full-service carriers have their pros and cons—it all comes down to personal travel style. I'll cover what to do once you reach the city in separate itinerary guides!
