Do you have any tips for my flight to Seia?
We've got the lowdown on how to make your flight an enjoyable experience. Follow our top tips and you'll be speeding through the airport and seeing the best of Seia in next to no time. What to pack in your hand luggage:

  • The secret to having a stress-free travel experience is to pack ahead. So, let's start with the essentials: passport, official ID, cash and vital medications. Next, bring on board items that'll help keep you busy, like some electronic devices or a thrilling book. It's also wise to bring your chargers, a comfy neck pillow and a pair of earphones. Last but not least, don't forget to toss in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like a pocket knife, and dangerous goods which are explosive or flammable, such as aerosols and poisons, are also banned.

What to wear on a flight:

  • Your main aim is to be as comfortable as possible. Go for flat, closed-toe shoes, dress in loose, breathable clothing and don't forget to bring a jacket in case you get chilly in the cabin.
  • 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 foot and leg exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Seia?
The trick is to be prepared before you reach airport security. That way, you'll be stepping onto that plane to Seia in the blink of an eye. Follow these tips and get your trip off to a spectacular start:

  • Security personnel first need to determine that you have a valid ID and boarding pass before anything else. Keep them within easy reach.
  • Your belt, jacket, keys and other small items, like coins, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • All your electronic gadgets, including your phone and laptop, must also be scanned.
  • Don't forget to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll be asked to remove your shoes to be X-rayed, so wearing slip-on shoes is always a good idea.
  • Knives and other sharp items can't be taken on board. They'll be confiscated at security, so pack them in your checked bags.
