Do you have any tips for my flight to Earth City?
Depending on where you're coming from, your flight to Earth City could be completely stress-free or it could go on forever. We've compiled some useful hints that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to pack in advance. First up, the essentials: passport, travel documents, cash and any vital medications. Next, bring on board items that'll help pass the time, like some electronic devices or a good book. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of earplugs. And of course, don't forget to toss in toiletry items like a toothbrush, lip balm and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your main concern when choosing what to wear during your flight. Loose clothing is a sensible option, as are flat, slightly roomy shoes.
  • Deep vein thrombosis (DVT) is a risk on long-distance 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 Earth City?
The secret is to be prepared before you arrive at the security gate. That way, you'll be hopping onto that plane to Earth City in no time at all. Follow these helpful tips and get your vacation off to a spectacular start:

  • First things first. Your boarding pass and passport will need to be shown to airport security personnel. Keep them within easy reach so you don't hold up the line.
  • Time to strip down. Well sort of. Your jacket, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • All electronic gadgets, including your laptop and phone, are also required to be separately scanned.
  • Travelling with a new hand and nail cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're permitted to bring it with you in your carry-on bag.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you need to bring these kinds of items, pack them in your checked baggage.
