Do you have any tips for my flight to Seongnam?

  • What you pack in your hand luggage can mean the difference between a comfortable flight, and a restless one. Start with the important stuff, like your passport (or a valid ID) and your travel documents. Once they’re safely packed, put in any medications you might need. Next? It’s all about the comfort factor. A quality neck pillow, earphones and a juicy bestseller will help the time fly by while you’re soaring above the clouds.
  • There’s a lengthy list of items you should not pack in your carry-on bag too. Sharps, explosives and flammables are strictly prohibited in the cabin — they often include aerosol cans, flares, box cutters and razor blades. Some sporting equipment, like baseball bats and tennis rackets, also generally can’t go in your hand luggage. Your airline’s website will have all the details about what you can and can’t take on board.

What to wear on a flight:

  • Go for comfort before fashion when flying. Dress in layers and wear natural materials as they allow moisture and air to pass through and keep you cool. Cabin temperatures typically get cooler on long-haul journeys, so pack a hoodie or similar and always wear sneakers or enclosed shoes.
  • Consider wearing compression socks or tights to reduce the risk of deep vein thrombosis (DVT). This condition is a result of blood clotting that can be caused by long periods of sitting, especially on long journeys. Doing leg and foot exercises in your seat or wandering around the cabin are good ways to improve your circulation.

How can I get a cheap last-minute flight to Seongnam?
If you want to land a cheap last-minute flight to Seongnam, aim to be flexible. If possible, have some wiggle room with the dates you can travel. It’s also wise to keep your options open with your arrival and departure airports, choice of carrier, flight times and possible stops or layovers.
Where can I learn more about changing or canceling my flight to Seongnam?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
