The Customer Service department, particularly the baggage claim process, needs significant improvement. Currently, this department is only accessible via email, which makes resolving urgent issues difficult and frustrating. On December 8th, while traveling from Rochester, NY to Concord, NC, my elderly parent’s walker was never boarded onto the aircraft. This caused considerable frustration, stress, and disappointment during our travel. A mobility aid such as a walker is not optional—it is essential for my parent’s safety and independence. The failure to properly handle this item created a serious and avoidable issue. This situation significantly impacted our travel experience and highlights the need for better communication, accountability, and handling of mobility assistance devices. I hope this matter is taken seriously and that improvements are made to prevent similar incidents in the future.
