General unlocking reserve hangar - when?

[Andy]

When do you unlock your Reserve Hangars?

This would be quite handy for flying maps or events when you suddenly need a lot of the same aircraft, but it's quite expensive and I'm wondering at which point in my game it would make sense to start doing it?

When did you start spending greenies on it?

Thanks.

I unlocked one today. I wanted to buy a new plane and needed hangar space. My choice was to spend 1m coins to upgrade to Control Tower L8 to get another hangar for 30 greenies to make a space in reserve hangar. I decided to use the greenies option and keep my coins to spend on larger planes.

@Andy
Reserve hangars very important but the strategy of playing make you decide.
For me i start buy slots when i buy my first Giant.
