Tips for short-haul flights to Riverside

  • Pack light and skip checked bags—with budget airlines, traveling with just a carry-on is often the more economical choice. Maximize space by using mini toiletries, wearing your heaviest clothes, and planning your outfits thoughtfully. This approach also allows you to bypass the baggage claim wait upon arrival.
  • Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. Download your favorite TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself entertained. Remember to fully charge your devices before you board.
  • Arrive at the airport in plenty of time—even for short or domestic flights, it’s advisable to get to the airport at least 1.5 to 2 hours before your departure, taking into account traffic and security lines.
  • 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.

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

  • Select your seat in advance—for longer flights, choosing your seat is crucial for comfort. Full-service airlines often provide free seat selection once online check-in opens, typically 24–48 hours before your flight. Some airlines may allow seat selection even earlier.
  • 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 processes.
  • Relax at the airport—if you have some extra time, take the opportunity to browse the shops, find a coffee shop, 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 adjusting your sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
