• Do not eat anything during your long-haul flight, drink water
  • Sign up for most airline and hotel programs
  • Stay with one airline and rack up miles
  • Micromanaging different travel programs not worth it
  • Go with the usual, regular route cheaper ticket
  • Book tickets ahead of time
  • Pick the airport closest to the city
  • Wake up whenever you want to
  • Download offline maps and dictionaries
  • Hotels usually have cable, adapter, or charger to lend you

I think that's all I learned and practicing.
