Do you have any tips for my flight to Dallesport?
If you're poorly prepared, traveling can be overwhelming. But don't hit the panic button just yet. Follow these helpful hints for a pleasant start to your getaway in Dallesport. What to pack in your hand luggage:

  • The secret to having a hassle-free flight experience is to plan ahead. First up, the essentials: passport, boarding pass, bank cards and important medications. Next, take on board items that'll help while away those hours, like your laptop or a thrilling novel. It's also wise to pack your chargers, a comfy neck pillow and a pair of earplugs. Last but not least, don't forget to pop in toiletry items like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in one of the zippers of your hand luggage. Other restricted items include flammable or explosive substances, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your priority is to feel as comfortable as you can. Opt for a pair of slip-on shoes, dress in loose, natural-fiber clothing and remember to bring a jacket in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to improve your circulation.

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

  • Airport security personnel first need to determine that you have a valid ID and boarding pass before anything else. Have them within easy reach, ready for inspection.
  • Time to strip down. Well kind of. Your coat, belt, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-lock bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked bags.
