How to survive the flight to Sidell?
Depending on where you're coming from, your journey to Sidell could be as easy as pie or it could drag on forever. We've rounded up some useful travel tips that will help you start your unforgettable escape on the right foot.What to pack in your hand luggage:

  • The trick to having a pain-free flight experience is to pack ahead. Start with the essentials: passport, official ID, cash and any vital medications. Next, bring on board items that'll help keep you busy, like some electronic gadgets or a good book. It's also smart to pack your chargers, a neck pillow and a pair of headphones. Finally, don't forget to chuck in toiletries like a toothbrush, deodorant and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp objects, like your trusty pocket knife, and dangerous products which are flammable or explosive, such as spray paint, flares and fuels, are also banned.

What to wear on a flight:

  • Your number one priority is to make yourself as comfortable as you can. Layer yourself up in natural fibers and don't forget to pack a jacket in case it gets cool in the cabin. Pick a pair of roomy, flat shoes as it's possible that your feet and ankles will swell a little during the journey. Leave the high heels and heavy hiking boots in your checked luggage.
  • The condition known as DVT (deep vein thrombosis) can pose a risk on long-distance flights. It's the result of blood clotting due to poor circulation and inactivity. Doing regular leg and foot exercises in your seat helps to prevent this occurring. Wearing a good-quality pair of compression socks may also help.

How to get through airport security fast when flying to Sidell?
As seasoned travelers know, the secret is to be well prepared before you reach security. That way, you'll be hopping onto that plane to Sidell before you know it. Follow these helpful tips and get your trip off to a fantastic start:

  • Your travel documents and passport will need to be shown to airport security. Have them close by so you don't hold up the line.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like your earphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronics also need to go through the scanner.
  • Any gels or liquids, such as perfume or toothpaste, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), clear zip-close bag.
  • Slip-on shoes are a great footwear choice as you're less likely to be asked to remove them when passing through security. Boots and other heavy shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
