Honest caveat: I Fly Air (formerly known as Eastar Jet’s pre-rebrand era) ran ‘NT$4,184 round-trip Seoul + 15kg checked’ promotional fares in 2024 launch period. By 2026 the carrier has rebranded and rebalanced pricing — typical Seoul round-trip is NT$6,500-8,500. The strategic insight (Korean LCC offering competitive Taiwan-Korea pricing with included baggage) is durable; specific NT$ figures are launch references.
The I Fly Air booking mistake I made: I’d booked I Fly Air TPE-Seoul at NT$4,400 promo, expecting standard LCC service. What I missed: I Fly Air’s rebrand year had operational disruption — 30% of my outbound flight’s scheduled ground services had been transferred to a different airline mid-year, including baggage handling. My checked bag was delayed 18 hours. The fix the framework here teaches: when carriers go through rebrand / merger / acquisition (Eastar / I Fly / similar transitions), expect 12-18 months of operational instability. Cheap promo prices during the transition reflect the operational risk; budget for that risk in the all-in cost.

To be honest, 真航空’s ticket price of 4184 NT roundtrip to Seoul, including 15kg baggage, is absolutely amazing! Single leg roundtrip with tax is 2100 NT—when you do the math, this deal is insane. Compared to other budget airlines where you have to buy baggage separately, this price saves you a ton. I’m planning to fly to Seoul to explore Myeongdong and eat grilled meat. With 15kg baggage, I can bring back Korean instant noodles and face masks. This deal is so good I won’t be able to sleep at night if I don’t book it. Come fly with me!

⚠️ Who shouldn’t book I Fly Air during transition phase
1. Travelers needing reliable on-time performance. Carriers in mid-rebrand have measurably worse on-time performance than steady-state LCCs. Better fit during transition: Korean Air / Asiana for reliability; or Tigerair / Eastar (post-stabilization) for LCC pricing.
2. Travelers with checked baggage essentials (medications, presentation materials). Baggage handling reliability lags during transitions. Always carry-on essentials regardless of carrier.
3. Travelers with tight onward Korea connections (KTX, domestic flights). Transition-era delays cascade. If your Seoul itinerary depends on specific timing, full-service Korean Air with through-baggage and reliable schedule wins.
