How to survive the flight to Declo?
We’ve rounded up all the info you need to make your flight a pleasant experience. Follow our insider tips and you’ll be speeding through the airport and having a blast in Declo in no time at all.What to pack in your hand luggage:

  • The trick to having a hassle-free flight experience is to pack in advance. Start with the essentials: passport, boarding pass, credit cards and medications. Next, take on board items that’ll help while away those hours, like some electronic gadgets or a thrilling novel. It’s also smart to bring your chargers, a quality neck pillow and a pair of headphones. And of course, don’t forget to pop in toiletries like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your Swiss Army knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and gasoline, are also prohibited.

What to wear on a flight:

  • The answer to a comfortable flight is as simple as the clothes you wear. Prepare for temperature changes by bringing layers. That way you’ll stay nice and warm if the cabin gets chilly. Shoes like sandals and heels are best left for other occasions. Instead, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • The result of sustained periods of immobility, DVT (deep vein thrombosis) is a serious condition that can affect passengers during long flights. The good news is there are ways to reduce your risk of developing it. Stay well hydrated, walk around the cabin whenever possible and wear compression tights or socks.

How to get through airport security fast when flying to Declo?
As savvy travellers know, the secret is to be prepared before you arrive at security. That way, you’ll be boarding that plane to Declo in no time flat. Follow these helpful tips and get your trip off to a flying start:

  • Airport security personnel first need to know that you have a valid ID and matching travel documents before anything else. Have them within easy reach, ready for inspection.
  • Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Personal belongings like your belt, coat and headphones will be required to go through the machine.
  • For just a few minutes, you’ll need to unplug from technology. Your laptop, phone and any other electronic gadgets will also need to be sent through the scanner.
  • Remove all liquids and gels from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won’t be allowed on board.
