☀️ Daily Booking & Flying Advice: Timing Your Purchase and Departure

Beyond the months, the specific day you book and the day you choose to fly can also impact your fare.

• Best Day to Book:
• • Historically, Tuesday and Wednesday afternoons are often cited as the best times to find cheaper flights. This is when airlines release new deals or match competitors' prices after weekend demand settles.
• Best Day to Fly:
• • Mid-week flights (Tuesday, Wednesday, Thursday) are generally cheaper than weekend departures (Friday, Saturday, Sunday).
  • Early morning or late-night (red-eye) flights can also be more affordable as they are less convenient for most travelers.
  • For the South Korea to Taiwan route, direct flights are frequent and usually the most convenient. Consider airlines such as Korean Air, Asiana Airlines, China Airlines, EVA Air, Jeju Air, T'way Air, Jin Air, Air Busan, Eastar Jet, and Tigerair Taiwan.

✨ Tactical Tips for Savvy Travelers

Maximize your chances of finding a great deal with these strategic approaches:

• Be Flexible with Dates: If your travel dates are flexible by a few days, you can often find significantly lower fares. Use Trip.com's flexible date search options to compare prices across a wider range.
• Consider Nearby Airports:
• • Departure: While Seoul Incheon (ICN) is the primary international hub, consider Busan (PUS) or Jeju (CJU) if you're starting your journey from those regions.
  • Arrival: Taipei Taoyuan (TPE) is the main international airport, but Taipei Songshan (TSA) offers convenience closer to the city center and can sometimes have competitive fares. Kaohsiung (KHH) is another option for southern Taiwan.
• Set Up Price Alerts: Trip.com allows you to set up price alerts for your desired route. You'll receive notifications when the fare changes, helping you snag a deal as soon as it appears.
• Browse in Incognito Mode: While not always a guaranteed money-saver, browsing in incognito/private mode or clearing your browser cookies can sometimes prevent dynamic pricing algorithms from showing you higher prices based on your search history.
• Look for Package Deals: Sometimes, bundling your flight with accommodation on Trip.com can result in greater overall savings than booking each component separately.
• Consider Budget Airlines: Low-cost carriers (LCCs) like Jeju Air, T'way Air, Jin Air, Air Busan, Eastar Jet, and Tigerair Taiwan often offer competitive base fares. Be mindful of additional costs for baggage, seat selection, and in-flight meals, which can add up.
