Turkish Airlines does not appear to have a dedicated, physical office in Reno, NV, but you can manage bookings and get support online at turkishairlines.com, via their mobile app, by calling their main customer service number (+1-866-829-1086 for HQ) or the Los Angeles office (potentially +1-866-829-1086), or by using their WhatsApp service for immediate help. For Reno-specific flight needs, check the Turkish Airlines website or app for airport support if flying from there, or rely on their digital channels for all booking changes and inquiries.
