Next, you'll need some extra in-flight entertainment to while away the hours. A juicy novel and a phone filled with your favourite shows are good options. If you plan to catch more than just forty winks, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some deodorant to ensure you touchdown looking fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, pocket knives, fuel and fireworks. Sports equipment like baseball bats, and items that could injure passengers, such as swords and guns, can't come on board with you either. > > > What to wear on a flight: > > > - Comfort should be your main priority when deciding what to wear during your flight. Loose, breathable clothing is a wise option, as are enclosed shoes like sneakers. > - Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights. ### How to get through airport security fast when flying to Mountain Ash? > - Your travel documents and ID will need to be shown to airport security personnel. Have them easily accessible so you don't hold up the line. > - The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt. > - All electronic devices, including your tablet and phone, will also need to be scanned. > - Any gels or liquids, such as lip balm or cologne, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag. > - It's also possible you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a good idea. > - Airlines will not allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage. __Flights to Mountain Ash information__ | Destination airport | Cardiff Intl. | | ----------------------------- | ------------- | | Destination airport IATA code | CWL | | Destination city name | Cardiff | | Return price | £34 | ## Trending flights to Mountain Ash Prices were available within the past 7 days and start at £17 for one-way flights and £34 for round trip, for the period specified.
