How do you survive a 15-hour flight?

Surviving a 15-hour flight is about a three-part strategy: pre-flight preparation (choosing the right seat, packing smart), in-flight management (hydration, movement, strategic sleep), and a smart landing plan (immediate connectivity, resisting naps). Prioritize comfort with layers, compression socks, a neck pillow, and noise-canceling headphones. Stay hydrated and get up to stretch every 1-2 hours.
