So, let's start with the basics: passport, travel docs, credit cards and any vital medications. Next, take on board items that'll help while away those hours, like some electronic gadgets or a few magazines. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of headphones. And of course, don't forget to squeeze in toiletries like a toothbrush, cleansing wipes and a spare set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Put all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your trusty pocket knife, and products which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also banned. > > > What to wear on a flight: > > > - Comfort should always be the goal when selecting what to wear on your flight. Consider your footwear choice with care too, as swelling of the feet and ankles are a common side effect of flying. Slightly roomy, flat shoes work well. > - The serious condition called deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to inactivity and poor circulation. Doing leg and foot exercises in your seat is a great way to prevent this from happening. Wearing a quality pair of compression socks or tights also helps reduce the risk. ### How to get through airport security fast when flying to Leinster? > - Airport security personnel first need to know that you have a valid ID and boarding pass before you're allowed to proceed any further. Keep them within easy reach. > - Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. No need to worry though, you'll be back online in no time. > - Any gels or liquids, such as perfume or toothpaste, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), clear zip-lock bag. > - Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy-style shoes are often subjected to additional screening. > - Sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked baggage. __Flights to Leinster information__ | Destination airport | Incheon Intl. | | ----------------------------- | ------------- | | Destination airport IATA code | ICN | | Destination city name | Seoul | | Roundtrip price | CA $246 | \*Available to Expedia members.
