Two years a go, i bring Yonex 951W on my way back from HKG to Jakarta. The security guards forbid me to hand carry my bag and asked me have it checked in as baggage. I inform them that there are 4 rackets inside and i am afraid that if i checked it in as baggage, rackets would be crushed. They informed me that they will take a good care of it. However, i inform them that i have no worries in HKG airport but in Jakarta Airport. I am afraid that it will got crushed there. At the end, they let me hand carry it. Additionally, i also have 951W hand carried while i am traveling from Beijing to Shanghai, then from Shanghai to Guangzhou. No questions from the security guard.
