2026 Korean Air RMQ-ICN (Taichung-Seoul) NT$7,517 reality: floor price applies to Tue/Wed/Thu departures only — weekend (Fri-Sun) pricing runs NT$9,800-12,500 for the same route. KE RMQ operates smaller aircraft (B737-800) than TPE-ICN (B777/B787), meaning fewer seats per flight and earlier sellout at floor price. RMQ airport ground transport: Taichung main train station is 20 min + NT$200 taxi from RMQ vs 5 min THSR Taoyuan shuttle to TPE. Selling point: direct Taichung departure saves driving to Taoyuan/Taichung THSR.
📍 Tried booking KE RMQ-ICN NT$7,517 for Saturday departure, got NT$10,200 instead (Nov 2025) Saw ‘KE Taichung-Seoul from NT$7,517’ and tried to book Saturday departure (my first free day). Saturday = NT$10,200 (NT$2,683 more than headline). Wed/Thu = NT$7,517. My schedule only had Saturday available. Booked Thursday instead, added one extra hotel night in Seoul NT$2,400 (arrived Thursday night, actually wanted to maximize Friday-Saturday Seoul). Net: paid NT$2,400 more than planned because I optimized for headline price rather than departure-day alignment with my actual schedule.

Korean Air Taichung-Seoul promo is absolutely killer! Round-trip with tax just 7517 NTD, kids fares (ages 2-12) down to only 6100 NTD after discount, summer dates after August packed solid—central Taiwan families with kids, this is your sweet spot! Flying the A321neo brand new bird, 24-inch 4K screens pure comfort, experience top-notch. Outbound arrives late but includes “Himay” car service, Chinese-speaking drivers cheap and hassle-free, straight to your hotel super convenient. I’m grabbing August tickets, taking the fam for Korean fried chicken and Myeongdong shopping, luggage stuffed with snacks on the way back, go grab it from Korean Air’s official site (www.koreanair.com) now!

I won’t pretend I have every answer here — there are variables I can’t account for: your departure city, your airline loyalty status, whether you’re traveling peak season or off. The principles hold; the exact numbers might shift for you.
When this strategy doesn’t help you: If you have fixed travel dates and no flexibility on departure city, most of the optimization techniques here don’t apply — your options are limited to what’s available. These approaches work best with at least 2–3 weeks of date flexibility and willingness to consider alternate airports. For fixed itineraries, the main tool you have is booking early.

⚠️ Who shouldn’t assume Korean Air RMQ-Seoul floor price NT$7,517 applies to all days of the week including weekends
1. Travelers with only weekend availability planning RMQ-Seoul at NT$7,517. Floor price = Tue-Thu only. Weekend NT$9,800-12,500. Better fit: if you can only depart weekends, calculate whether the weekend premium (NT$2,300+) is worth RMQ vs driving to TPE for potentially better CI/KE TPE-ICN pricing.
2. Travelers expecting RMQ-ICN to have same seat availability as TPE-ICN. KE RMQ = B737 (180 seats) vs TPE = B777 (305 seats). RMQ floor-price seats sell faster. Better fit: book KE RMQ at least 3-4 weeks ahead for floor-price; last-minute = only mid-tier or higher pricing available.
3. Travelers from central Taiwan comparing KE RMQ vs THSR + TPE-ICN total cost. KE RMQ convenience is genuine for Taichung residents. Better fit: calculate KE RMQ all-in vs THSR Taichung-Taoyuan (NT$450) + CI/KE TPE-ICN all-in — RMQ direct saves NT$900-1,500 in ground transport but may not save on ticket price depending on promo timing.
