Do you have any tips for my flight to Earth City?
Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well enough. We've made a list of handy travel tips that will get your Earth City vacation started on the right note. What to pack in your hand luggage:

  • It's simple — first, put in your passport, important documents, bank cards and daily medications. Next, you'll want some entertainment to while away the hours. A thrilling book and a phone crammed with your favourite shows are always good options. If you hope to take a quick nap, a neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a few toiletry items so you'll arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, knives, aerosol cans and flares. Sports equipment like golf clubs, and items that could harm passengers, such as pepper spray and guns, are also banned from the cabin.

What to wear on a flight:

  • Your top priority is to be as comfortable as you can. Go for easy-to-remove footwear, dress in loose, natural-fibre clothing and don't forget to bring a pullover in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Earth City?
A little pre-planning before you arrive at the airport will help make your getaway to Earth City a piece of cake. Below you'll find some useful tips and tricks for a speedy journey past security:

  • Airport security personnel first need to verify that you have a valid ID and travel documents before you're allowed to proceed any further. Have them close by, ready for inspection.
  • Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and earphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Want to bring along your favourite perfume or cologne? No problem. As long as the volume is no greater 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.
  • There's a possibility that you'll need to remove your shoes for scanning, so wearing lightweight sneakers is always a clever idea.
  • Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you must bring these kinds of items, check them in.
