Do you have any tips for my flight to Darby?
Depending on where you're coming from, your journey to Darby could be as easy as pie or it could drag on forever. We've rounded up some useful hints that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:
  • A plane ride can be a cruisy experience if you pack the right things. Firstly, you'll want a few basic toiletries, such as a toothbrush and lip balm, a fresh set of clothes and something to read. Secondly, find a spot in your hand luggage for your phone and charger, your important medications and maybe a comfy neck pillow too. Lastly, and most importantly, remember to take your passport, travel papers and your bank cards.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, knives, fireworks and fuel. Sports equipment like golf clubs, and items that could harm passengers, such as pepper spray and guns, won't be allowed on board either.
What to wear on a flight:
  • Comfort should be your number one priority when choosing what to wear during your flight. Loose, breathable clothing is a smart choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Darby?
The simple answer is — be prepared. We've put together some top tips for a speedy trip through security. Look out Darby, here you come:
  • Be sure to have your ID and travel documents within easy reach. They're the first things you'll be asked to present to airport security.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • Your electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry, you'll be back online in no time.
  • Any gels or liquids, such as shampoo or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won't be allowed on board and will be confiscated.
