How to save money on a flight to South Korea

Getting some of the best deals on flights to South Korea is all about timing and flexibility. Here are some key tips to help you save:

1. Compare flight options—use Expedia's search tool to compare airlines, routes, direct vs. non-direct flights, and flight times. You can also sort by price to find the most affordable options.
2. Set up price alerts—stay up to date on fare changes by using Expedia's Price Tracker. Receive alerts when fares drop for your selected route.
3. Bundle and save—book a flight and unlock a hotel deal on Expedia*, or explore our South Korea hotel and flight deals.
4. Travel during shoulder season-peak travel periods tend to push the flight fares a little higher than usual. Traveling outside of these busy periods can help you find more competitive prices while still being able to enjoy good weather and lesser crowds.
5. Be flexible with your travel dates-if your schedule allows it, try and search for a few different departure and return dates as this may help you find lower fares.
6. Consider economy fares-if you're traveling light and don't need extras like seat selection or additional baggage, opting for a basic economy fare can be a simple way to keep costs down. Just make sure to check what's included in the flight ticket before confirming your booking.
7. Think about luggage—it's important to check the airline's baggage policies to find the best value. That may be paying for an additional carry-on bag or booking a ticket with checked luggage included. Either way, double-check your baggage allowance before confirming your booking to avoid excess baggage fees at the airport.
8. Earn miles—you can earn airline miles when you book with Expedia. Make sure to select your frequent flyer program and enter your program number when confirming your booking to get more value from your trip.

Tips for short-haul flights to South Korea

For quick getaways, efficiency is key. Here is how to make your short-haul journey smoother:

• Pack light and skip checked bags—when flying with budget airlines, it's often more economical to travel with just a carry-on. Maximize your space by bringing mini toiletries, wearing your bulkiest clothing, and planning your outfits wisely. This strategy also allows you to bypass waiting at baggage claim upon arrival.
• Early check in—most airlines allow you to check in online at least 24 to 48 hours before your flight's departure. This can save you time at the airport, and you may even secure a preferred seat without incurring additional costs.
• Bring your own entertainment—many short-haul flights do not provide in-flight entertainment. Download your favorite TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself entertained. Remember to charge your devices fully before boarding.
• Arrive early—even for short flights, it's advisable to arrive at least 1.5 to 2 hours before departure, taking into account traffic and security line delays.
• Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money while at the airport.

Tips for long-haul flights to South Korea

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

• Select your seat in advance—for longer flights, choosing your seat is essential for comfort. Full-service airlines may allow free seat selection once online check-in opens, typically 24 to 48 hours before your flight. Some airlines may permit earlier seat selection, but an additional fee may apply.
• Arrive early—plan to reach the airport at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
• Relax at the airport—if you have extra time, explore the shops, find a coffee shop, or unwind at the gate or in a departure lounge if you have access.
• Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
• Dress comfortably—the journey will be long, so opt for loose, comfortable clothing and layers, as cabin temperatures can fluctuate.
• Stay hydrated—bring a refillable water bottle and drink plenty of water to ensure you remain hydrated, so you feel your best upon arrival.
