JetBlue doesn't have a direct customer-facing office in Prague instead, they use local partners like JetBee Czech s.r.o. for local representation (at K Letišti 1073/25, Praha 6) and handle most customer service through their website, app, or call centers (1-800-JETBLUE), especially for booking and managing flights. For specific inquiries related to bookings or issues, you should use JetBlue's online tools or call their main contact numbers.
