Do you have any tips for my flight to Roche Harbor?
If you're not prepared, airports and flying can be overwhelming. But there's no need to hit the panic button just yet. Follow these tips and tricks for a trouble-free start to your vacation in Roche Harbor. What to pack in your hand luggage:

  • Flying can be a stress-free experience if you bring the right stuff. Firstly, you'll want a few basic toiletries, such as a toothbrush and lip balm, a spare pair of socks and a good book. Secondly, leave space in your bag for your mobile phone, a charger, any vital medications and maybe a blow-up neck pillow as well. Last, but definitely not least, remember to bring your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a sharp object hiding in one of the zippers of your hand luggage. Other prohibited items include explosive or flammable goods, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your aim here is to be as comfortable as you can. Opt for slip-on footwear, dress in loose, breathable clothing and remember to bring a pullover in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Roche Harbor?
The answer is simple — be prepared. We've rounded up some top tips for a hassle-free trip through airport security. Look out Roche Harbor, here you come:

  • Security personnel first need to see that you have a valid passport and matching travel documents before you can proceed any further. Have them within easy reach, ready for inspection.
  • The X-ray machine is up next. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your phone and laptop, must also be scanned separately.
  • Any liquids or gels, such as toothpaste or perfume, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-lock bag.
  • There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed in the cabin.
