Standard gel packs: 4-8 hours. Phase-change packs: 10-18 hours. Vacuum-insulated containers with gel packs: up to 24 hours.

Can I bring multiple ice packs?

Yes. There is no limit on the number of frozen ice packs in carry-on. Declare them with your medical liquids at the checkpoint.

TSA Rules for Ice Packs

Ice packs must be frozen solid when presented at the TSA checkpoint. This is the single most important rule. Partially melted packs are treated as liquids and may be confiscated.

Gel Phase-Change Packs vs Regular Ice

Phase-change packs maintain a steady temperature longer than water-based packs. They transition between solid and liquid at a specific temperature (usually 4°C), providing more consistent cooling.

EU Rule from June 2026

Starting June 2026, EU airports require gel packs to be under 100ml unless you carry a digital medical certificate. This applies to all Schengen-zone airports. Non-EU travelers must comply with this rule on connecting flights through Europe.
