Good to hear umbrellas are acceptable, but not in the Philippines. Not even small fold up ones. I found this out when I was flying to Hong Kong from the Manila and was told at security I had a weapon. As I had lots of time I decided to return to check in and gave them my Ambarella to check as baggage. After some argument where they wanted me to box it they checked it' through. It had for me Become more or less a joke. I couldn't believe it when it came out unscathed all lonely on the conveyor belt.
