Travelling through Brussels, my saline solution, which is legal for US TSA, was declared illegal by airport security.

Are medical exclusions different for USA Travel and Foreign travel?



Best Answer

Just so we are clear. Security at airport(s) in Brussels is not the responsibility of the US TSA even if flight is coming from or going to the US.

If you're interested you can go to the Brussels Airport Site on Bags & Security for more details on what is and is not allowed on board which among other restrictions states:

  • Medicines and dietary supplements for use during the flight are also allowed (ask your doctor for a certificate to prove their necessity).

Saline Solution isn't a dietary supplement nor it is a medicine so if you require it on board you should probably have a doctor write a letter authenticating that you require to have Saline with you at all times for a medical reason.

There are exception to the Liquid and Gels Policy but Saline still doesn't qualify. So if you brought a large bottle of it with you on board the security personnel seem to be well within their right to disallow it.

What is the 3 1 1 rule at airport security?

Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels and aerosols.

Does the 100ml rule still apply?

The main rule to remember is that you must not take any more than 100ml of a restricted liquid into the cabin of a plane, and those liquids should be placed into individual 100ml containers. Any liquid that you need more than 100ml of should be packed in your hold luggage.

Is 100ml TSA approved?

You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item.

Why is it called the 3 1 1 liquids rule?

The 3-1-1 Rule refers to three core components that govern how many liquids you can bring in your carry-on bags: Each liquid must be in a 3.4-ounce or less container ("3"), all containers must be placed inside one clear quart-sized plastic bag ("1"), and each passenger is only allowed one plastic bag ("1").

Answer 2

No, the rules are not different in this context.

Currently the rules for liquids are exactly the same in US and EU.

The rules are:

  • Containers up to 100mL (3.4oz)
  • In clear bag up to 1L (1 quart)
  • One bag per passenger

Also in both in US and EU exceptions apply, but they are essentially the same:

  • US – „Medically required liquids, such as medications, creams and breast milk, are permitted to be brought on board an aircraft.”
  • EU – „Medicines and baby food are permitted, if demonstrated that these are essential during the flight.”

The rest is up to security screening officer, his interpretation of the rule and your ability to convince him that liquid is „medically required”. I imagine that outcome would vary even with different TSA agents at same airport. You just got lucky once.
