  • Pack light and skip checked bags—when flying with budget airlines, traveling with just a carry-on can often save you money. Maximize space by using mini toiletries, wearing your bulkiest clothing, and planning your outfits wisely. This also means you can avoid the hassle of waiting at baggage claim after your flight.

  • Arrive at the airport in plenty of time—for short or domestic flights, it's advisable to arrive at least 1.5 to 2 hours prior to departure, allowing for traffic and security line delays.
  • Bring your own snacks and water—pack some snacks along with a refillable water bottle to stay hydrated and save money while at the airport.

  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take the opportunity to explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and available.
  • Adjust to the new time zone mid-flight—begin to sync your body clock by changing your watch and sleep schedule to align with your destination's time zone. Try to either sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
