How to survive the flight to Hermiston?
We’ve pulled together all the info you need to make your flight a stress-free experience. Follow our tips and tricks and you’ll be hightailing it through airport security and seeing the best of Hermiston in no time.What to pack in your hand luggage:

  • A plane trip can be a comfortable experience if you carry the right stuff. Firstly, you’ll want a few toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare set of clothes and a good book. Secondly, leave space in your bag for your electronic gadgets, chargers, any daily medications and perhaps a proper neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like box cutters, razor blades, spray paint and fireworks. Sports equipment like baseball bats, and items that could injure passengers, such as swords and guns, are also banned from the cabin.

What to wear on a flight:

  • The answer to a comfortable flight is as simple as your choice in clothes. Prepare for temperature changes by layering up. That way you’ll stay nice and warm if the cabin gets too cold. Shoes like sandals and heels are best left in your suitcase. Even though they may be your favourites, go for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • Unfortunately, one risk of long-distance flying is developing DVT (deep vein thrombosis), a blood clotting condition caused by extended periods of inactivity. To prevent this, make the most of every opportunity to wander around the cabin. Compression socks and tights are another great idea to help reduce this risk.

How to get through airport security fast when flying to Hermiston?
The answer is simple — be organised. We’ve put together some useful tips for a fuss-free trip through airport security. Look out Hermiston, here you come:

  • Be sure to keep your ID and boarding pass someplace easily accessible. They’ll be the first things you’ll be asked to present to security.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • For just a few moments, you’ll need to unplug from technology. Your phone, tablet and any other electronics must also be sent through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board must be no larger than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • It’s also possible you’ll be required to take your shoes off to be X-rayed, so wearing slip-on shoes is always a smart idea.
  • Airlines won’t allow any sharp objects in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage.
