Flew a few years ago to Spain. Arrived and unpacked bikes and my mates large chainring was bent at right angles so god knows what had happened.
On the way back, not really easy jets fault, the security at malaria airport didn’t give me chance to fold the bike bag straps up, put it through the scanner and the straps jammed, they just sliced through them with a knife. Leaving me with a bag with no straps. No time to argue.
