Do you have any tips for my flight to Port Isabel?
We've got the lowdown on how to make your flight an enjoyable experience. Follow our top tips and you'll be hightailing it through the airport and seeing the best of Port Isabel before you know it. What to pack in your hand luggage:

  • Travelling on a plane can be a great experience if you bring the right gear. Firstly, you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh set of clothes and a magazine or two. Secondly, find a spot in your bag for your laptop, a charger, your important medications and perhaps a comfy neck pillow too. Lastly, and most importantly, be sure to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, aerosol cans and bleaching agents. Sports equipment like baseball bats, and objects that could harm passengers, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick closed-toe, flat shoes like sneakers.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Port Isabel?
Being organised before you arrive at the airport can make your trip to Port Isabel quick and painless. Read through our handy hints for a speedy journey through security:

  • First things first. Your travel ID and boarding pass will need to be presented to security personnel. Keep them within easy reach to avoid fumbling around for them.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
  • All electronic devices, including your phone and tablet, are also required to be scanned.
  • Travelling with a new cologne? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on baggage.
  • There's a chance you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a smart idea.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, put them in your checked luggage.
