How to survive the flight to Port Jefferson?
Depending on where you’re coming from, your flight to Port Jefferson could be a breeze or it could go on forever. We’ve put together some useful hints that will help you start your next unforgettable escape on the right foot.What to pack in your hand luggage:

  • Flying can be a cruisy experience if you take the right gear. First things first, you’ll need basic toiletries, such as a toothbrush and lip balm, a fresh change of clothes and a magazine or two. Secondly, find a spot in your carry-on bag for your phone and charger, any daily medications and maybe a cosy neck pillow too. Lastly, and most importantly, don’t forget to take your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don’t have sharp or pointed objects hiding in one of the compartments of your hand luggage. Other banned items include explosive or flammable substances, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of an aircraft are not the best place for a fashion parade. Don comfortable layers and pack a cardigan as it tends to get cool inside the cabin. Enclosed, flat shoes are also recommended.
  • Caused by sustained periods of inactivity, DVT (deep vein thrombosis) is a blood clot condition that can affect passengers on long-distance flights. But the great news is there are ways to significantly reduce the risk of developing it. Stay well hydrated, wander around the cabin as often as you can and wear compression socks or tights.

How to get through airport security fast when flying to Port Jefferson?
The secret is to be well prepared before you reach airport security. That way, you’ll be boarding that plane to Port Jefferson in no time at all. Follow these tips and get your trip off to a flying start:

  • First things first. Your travel documents and ID will need to be inspected by security personnel. Have them close by so you don’t hold up the queue.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They’ll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like laptops and phones will also have to go through the machine for inspection. No need to worry though, you’ll be back online soon enough.
  • Any liquids or gels, such as perfume or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you’re less likely to have to remove them when passing through security. Big boots and heavier-style shoes are often subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won’t be allowed on board and will be confiscated.
