Topic Explanation:
The forum topic is about flying with a colostomy and the concerns related to security and in-flight issues. The original poster's friend is worried about potential problems with security, using the restroom during the flight, and the fear of the colostomy bag "blowing up" during the flight.

Advice and Insights:
- When going through airport security, it's helpful to inform the TSA officers about wearing an ostomy appliance and offer to show it if needed.
- It's advisable to eat lightly before the flight to minimize output and to empty the pouch before boarding the plane.
- Carrying extra supplies, a change of clothing, and wet wipes in the carry-on luggage is recommended.
- Opting for a private screening is an option if it provides peace of mind.
- TSA Precheck can be beneficial for frequent travelers as it often involves going through the metal detector instead of a scanner.
- It's important to be prepared, inform TSA about the ostomy, and comply with their procedures during the security check.
- Ostomy bags do not inflate during the flight, so there's no need to worry about that.
- It's advisable to wear loose clothes and underwear and to empty the pouch more often than necessary during the flight.
- It's recommended to carry a letter from a doctor explaining the need for ostomy supplies, and to carry supplies in the carry-on to avoid potential issues with checked luggage.
- Pouches with filters are available for ostomates, but it's important to consider individual experiences and preferences with using them.
- It's advisable to be cautious with carrying scissors in carry-on baggage and to be prepared with precut seals in case the scissors are not allowed through security.
- Informing TSA about the ostomy and carrying a TSA card can be helpful, but some travelers have not experienced any issues without informing TSA.
- Choosing an aisle seat near the bathroom can be beneficial for quick access during the flight.
- Staying away from carbonated drinks and gas-inducing foods can help minimize potential issues during the flight.
