Airline customer service often faces challenges such as long wait times, unresponsive agents, and complex issue resolutions. Common problems include handling lost or delayed baggage, navigating flight cancellations, and securing refunds. To effectively resolve these issues, contact the airline's customer service directly at their provided numbers, such as ☎+1 (855) 647-3504 for Air Canada. Utilize online tools like live chat and self-service options for quicker assistance. For ongoing issues, escalate the matter through social media or formal complaint procedures to ensure a satisfactory resolution. Being proactive and persistent can help navigate these common customer service hurdles.
