General Travel Tips – 

  • Do Some Advance Planning – Confirm your travel details and make sure the name on your boarding pass and your government-issued ID match.
  • Pack with Security in Mind – Know what is and isn’t allowed in carry-ons and checked luggage by checking the TSA website. Also see if you qualify for the new TSA PreCheck program.
  • Get your Boarding Pass Early – Print it online before you arrive or use convenient check-in kiosks in the airport garage or at airline check-in counters. Passengers with only carry-on baggage can go directly to the security checkpoint. Passengers with luggage can go to airline bag-check points.
  • Check the status of your flight online or via email notification – Check the flight status page for updates online or through email alerts.
  • Arrive at least two hours before your flight – give yourself time to get through security.
  • Park in the Airport Garage – Save time, stay dry and be close. No shuttles, covered skybridges and you are right next to the terminal.

Tips for avoiding congestion on the drives
Below are some effective tips for avoiding the congestion:

  • THINK OPPOSITE! Pickup on the departure drive, drop-off on the arrivals drive – If traffic is congested, look for the opposite airport drive for relief. Try meeting your arriving guests one level up from baggage claim at the less-crowded departure drive. Those with only carry-ons can go straight out the ticketing level. For drop-offs, reverse it. Go to the arrivals drive and travelers only have to go up one level to ticketing. Remember, the busiest periods are mornings for departures and evenings for arrivals.
  • Don’t get stuck in traffic! -- Park on the Terminal Direct floor of the airport parking garage, the quickest and most convenient option for meeting passengers in the terminal, and pay just $4 per hour. Or use any other floor for $3 per hour.
  • Try the cell phone waiting lot -- A new cell phone lot opened just south of S. 170th Street exit from the Airport Expressway. When fully completed in June, the new lot will have 200 spaces specifically designed for easier circulation, along with better lighting, and free WiFi. Parking is free as long as drivers remain in their vehicle and can wait up to 30 minutes. Take advantage of the posted QR code to scan for the most recent flight arrival information. Remember, there is no parking or waiting allowed on the airport roadway shoulders.
