How to survive the flight to Kaiser?
Depending on where you're coming from, your journey to Kaiser could be simple and straightforward or it could go on forever. We've pulled together some tips that will help you start your next great adventure on the right foot.What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you carry the right gear. First things first, you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a clean set of clothes and a good read. Secondly, find a spot in your carry-on bag for your mobile phone, a charger, your medications and perhaps a quality neck pillow too. Lastly, and most importantly, be sure to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, aerosol cans and bleaching agents. Sporting equipment like bows and arrows, and items that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your priority when deciding what to wear on board. Consider your footwear choice with care too, as swollen feet and ankles are a common side effect of flying. Roomy, closed-toed shoes are always a smart option.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long-haul flights. The great news is there are proven ways to reduce your risk of developing it. Keep your fluids up, get up and wander the aisles as often as you can and wear compression socks or tights.

How to get through airport security fast when flying to Kaiser?
Being organized before your flight will make your trip to Kaiser quick and painless. We've compiled some handy tips and tricks for a speedy journey through security:

  • Security personnel first need to establish that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Have them within easy reach, ready for inspection.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronics, including your phone and tablet, must also be scanned.
  • Traveling with your favorite perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can bring it with you in your carry-on baggage.
  • There's a good chance you'll be asked to remove your shoes for scanning, so wearing slip-on shoes is always a wise idea.
  • Airlines will not allow any pocket knives or other sharp items in the cabin. If you need to bring these kinds of items, pack them safely in your checked baggage.
