| Glasgow to Dublin. The check in and flight itself was good. On time and reasonable. I am a cyclist and scientist and traveling for conference and training. I booked and paid for a bicycle. However, on return my bicycle carry box was damaged externally. I have had no offer of acceptance/not of liability, letter etc. When home (Glasgow), the bike frame had be damaged, which would have required a heavy force e.g. dropped form back of plane, heavy baggage dumped on top etc. The frame was unridable and needed replacing. I fly about 40 flights a year and have done for over 5 years with bike in this format with zero issues (mainly Air New Zealand and other Star Alliance carriers). OK. so occasionally some handling error may occur, this is life. However, I called, wrote, filled out online forms as recommended by AerLIngus. Replies were short and noted "please wait out team is reviewing it". I followed up 9 times over 2 months and still no response. I have now moved to my travel insurer for recovery of damage costs. Aer Lingus' baggage-ralated customer services is appalling 0.5 out of 10. It left a very sour taste and I would not travel Aer Lingus again nor can recommend this airline. If you do value your baggage and must travel with this poor airline, ensure you have it fully insured. reading other comments here, the airline has a baggage handling issue to sort out. Cheers.
