If passengers are at Quad City International Airport and you already pass the security checkpoints, it is straightforward to get around, as there is no more than one terminal. If a passenger wants to move between the gates or simply visit the airport, there are a variety of options.
Airport Shuttle Bus at MLI
G.O. Airport Shuttle and SuperShuttle are providers of the Quad City International Airport. Buses are situated outside of the secure area; passengers will have to clear security checkpoints one more time in your terminal to get to your flight.
Walking at MLI
It is also possible to walk to approach to the terminal, but a passenger must be aware to use time appropriately to get on time to their flight.
