What travelers love
  • Short Security Lines: Passengers consistently report fast security wait times, often under 15 minutes, and sometimes as low as 0-8 minutes for departing passengers. This is a significant advantage compared to major airports.
  • Efficient Immigration: For arriving international passengers, immigration wait times are also fast, typically ranging from 2-12 minutes, with US Citizens often experiencing even quicker processing.
  • Convenient Access to Major Hubs: SkyWest Airlines, operating as United Express, provides twelve round trips per week to Chicago O’Hare International Airport (ORD), offering access to United’s extensive domestic and worldwide route network. Cape Air also offers daily direct flights to St. Louis Lambert International Airport (STL), providing connections to national and international flights.
  • Expedited Security Options: The airport offers TSA PreCheck and Clear for expedited security screening.
  • Simplified Travel Experience: The airport features a single terminal designed for passenger convenience, offering a simplified experience from check-in to boarding.
Common complaints
  • Limited Amenities: While the airport has basic amenities like a comfortable waiting area, car rental services, and ample parking, it does not boast the wide range of amenities typical of major airports.
  • Increased Wait Times During Peak Seasons: During busy travel periods like July, August, and December, wait times can be 30-50% longer than average.

Bottom line: Decatur Airport offers a streamlined and efficient travel experience, particularly for those connecting to larger hubs like Chicago O'Hare and St. Louis Lambert. Its primary strength lies in its quick security and immigration processes, though travelers should be aware of potentially longer waits during peak travel months.
