How to get through airport security fast when traveling to Port Isabel
If you like the idea of spending more time at the airport cafes and less time navigating your way through security on your way to Port Isabel, follow these useful tips:

  • Be sure you know the location of your travel ID and boarding pass. You don't want to hold up the line when you're asked to hand them over.
  • You'll need to stop the tunes for a few minutes. Earphones and headphones must be taken off and put in a tray for X-raying. The same goes for items such as belts and heavy jackets.
  • Everyday electronics such as laptops, tablets and phones are always sent through the X-ray machine separately. Be sure to have them within easy reach.
  • When you get to the security checkpoint, you'll be asked to put all creams, gels and liquids in a separate bin for scanning. Make sure they're all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Airport security staff may instruct you to take off your shoes for the body scanner. Choose a pair that slip off easily. There's nothing more annoying than having to do up your laces over and over again.
  • Razors and knives are prohibited from entering the aircraft. Put them in your checked luggage to avoid them being confiscated at the security checkpoint.
