I have a bowling bag that holds 3 bowling balls that is within the weight limits set by the airlines. The problem I had with the bag when I flew to Texas 2 years ago was the length of the strap--too short! Since the strap was so short, the bag wanted to flip while pulling it (very aggravating). Since I will be flying to Reno this year to bowl in the National Tournament, I needed some way to make the strap long enough for me. I purchased this handle to lengthen the strap and it works like a dream! The bag no longer flips over.
