Do you have any tips for my flight to Adelphi?
If you're not prepared, travelling can be tough. But there's no need to hit the panic button just yet. Follow these tips and tricks and enjoy a trouble-free start to your holiday in Adelphi. What to pack in your hand luggage:

  • It's easy — first, pack in your passport, travel docs, cash and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling book and a phone crammed with your favourite movies are always good options. If you intend to catch forty winks, a comfy neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you arrive at your destination feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like a Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and fuels, are also prohibited.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer up with comfortable clothing and go for shoes that are closed-toe, flat and easy to slip on and off.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clots forming due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Adelphi?
Being prepared before your flight will make your getaway to Adelphi quick and painless. Check out our useful tips and tricks for a speedy journey through security:

  • Your boarding pass and travel ID will need to be presented to airport security personnel. Keep them handy so you don't have to dig around for them.
  • Time to strip down. Well kind of. Your coat, belt, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online before you know it.
  • Travelling with a new hand cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on baggage.
  • It's also likely that you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
  • Airlines won't allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, put them in your checked baggage.
