First up, the essentials: passport, boarding pass, credit cards and important medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a thrilling book. You'll also want to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Last but not least, be sure to pop in toiletries like a toothbrush, deodorant and a fresh change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Pack 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 millilitres) will be confiscated by security. Sharp objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and gasoline, are also prohibited. > > > What to wear on a flight: > > > - The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and go for shoes that are closed-toe, flat and easy to take on and off. > - The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression tights or socks. ### How to get through airport security fast when flying to Marblemount? > - Your ID and travel documents will need to be inspected by security personnel. Keep them someplace accessible so you don't have to dig around for them. > - The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic gadgets must also go through the scanner. > - Remove all gels and liquids from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag. > - Slip-on shoes are a great footwear choice as you're less likely to have to remove them when going through security. Big boots and heavier-style shoes are often subjected to extra screening. > - Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed on board and will be confiscated. __Flights to Marblemount information__ | Destination airport | Seattle - Tacoma Intl. | | ----------------------------- | ---------------------- | | Destination airport IATA code | SEA | | Destination city name | Seattle | | Return price | £303 | ## Trending flights to Marblemount Prices were available within the past 7 days and start at £294 for one-way flights and £304 for round trip, for the period specified.
