Smart timing, search engines, and stopover options are key to booking cheap flights to Korea in 2025.
A practical airfare-saving guide for international travelers heading to Korea.
For anyone planning a trip to Korea, finding an affordable flight is a smart first step. Based on the latest 2025 trends and booking data, here are strategies to help international travelers secure the best airfares.
Best time to book flights to Korea
Ideal booking window: 2 to 3 months before departure
Airfares tend to be 15–20% lower during off-peak months (March–May, October–November). For peak seasons (June–August, December–January), booking at least 3 months in advance is essential to grab the cheapest seats.
Tuesday and Wednesday departures are generally more affordable than weekend flights.
💡 Tip: Airfare prices often spike over the weekend. Search between Monday and Wednesday for better deals.
Choosing between low-cost and full-service carriers
Short-haul routes (e.g., Southeast Asia, Japan, China) are significantly cheaper with low-cost carriers (LCCs).
Popular Korean LCCs include Jeju Air, Jin Air, T’way Air, and Air Busan, with one-way tickets typically ranging from $80–$150 (as of June 2025).
For long-haul flights (USA, Europe), discounted fares are often available through promotional events by full-service airlines like Korean Air and Asiana Airlines, or their codeshare partners.
Use global flight comparison platforms
Take advantage of major flight search engines to compare prices and find deals:
| Platform | Key Features |
|---|---|
| Skyscanner | Flexible date and month comparison tools |
| Google Flights | Intuitive UI, price alert notifications |
| Kayak | Strong in LCC inclusion |
| Trip.com | Particularly effective for Asian low-cost fares |
📌 Search tips:
-
Select "flexible dates" to find the lowest fare options.
-
Include nearby airports to expand affordable flight options.
Consider stopover flights for bigger savings
Connecting flights can be 30–40% cheaper than direct ones.
Example: Bangkok → Taipei (stopover) → Incheon may offer a significant cost advantage.
Aim for layovers of 5–8 hours to avoid excessive travel fatigue.
Don’t miss airline promo deals
Full-service airlines like Korean Air and Asiana regularly offer limited-time promotions on their official websites.
Subscribing to their newsletters or creating a member account allows early access to deals. In some cases, round-trip fares have dropped up to 40% during the first half of 2025.
