Of course!
To travel with a water bottle, you simply need to empty it before going through security check at the airport. It's important to note that liquids in containers larger than 100 ml are not allowed in the cabin. However, once you've passed security, you can fill your water bottle in the boarding area and take it with you onboard the plane. This will allow you to stay hydrated throughout the flight. Remember to securely close your bottle to prevent any leaks during the journey.
