Bus from Edinburgh airport to Glasgow

[Summersoon23]

Will be on a flight arriving back about 7pm ish in a few weeks.
Does anyone know the bus number, frequency and where to get it at Edinburgh airport for going to Glasgow.
Much appreciated- I find online bus info confusing!
Thank you!

It's the Air bus. The timetable is on Megabus's website and it is half hourly 25 and 55 minutes past the hour, except there isn't a 19.25.
At the airport, follow signs for the buses and the bus stops are marked as to which bus stops there.

Thank you!

Stance D outside the terminal. It's operated by Citylink not megabus (you can buy tickets online through either but it's also fine to buy on board the prices don't vary that much ime).

Here is the timetable. 25 and 55 past the hour at that time of night.
