Real-Time Flights Database

Hi,

I need some help optimizing a flight database I built for a project. The file is attached. Tab 1 (Updated Flight list) is pulling flight times for a website(starts on row 92). The second tab, "Selection" is a filter based on a drop down menu of all airlines.

I need help updating the data. Ideally, I would like for the data to update in real-time (instead of having to constantly hit the refresh button). If this can't be done in real time, is there a formula or code that can be created to automatically refresh the data in 5, 10, or 15 second intervals?

Can this be done?

Thanks very much for the help!
