Do you have any tips for my flight to Udu?
If you're poorly prepared, airports and flying can be overwhelming. But there's no need to panic. Follow these tips and tricks for a comfortable start to your time in Udu. What to pack in your hand luggage:

  • Travelling on a plane can be easy if you bring the right stuff. Firstly, you'll want a few basic toiletry items, such as a toothbrush and hairbrush, a clean set of clothes and a magazine or two. Secondly, find a spot in your bag for your laptop, a charger, medications and perhaps a proper neck pillow too. Lastly, and most importantly, don't forget to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like box cutters, razor blades, spray paint and fireworks. Sporting equipment like ice skates, and objects that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

  • Your priority is to be as comfortable as you can. Go for a pair of flat, closed-toe shoes, dress in loose, natural fibers and don't forget to take a jacket in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT) can pose 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 Udu?
Being organised before your flight can make your getaway to Udu easy and painless. We've compiled some useful tips for a stress-free journey past security:

  • Keep your boarding pass and ID within close reach. They're the first things you'll be asked for by security.
  • Next up, both you and your hand 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 coat, belt and earphones need to go through the machine.
  • All electronic gadgets, including your phone and tablet, will also need to be scanned.
  • Any liquids or gels, such as perfume 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.
  • There's a chance you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board.
