[Grammar] By preposition

[longki]

Hello, I wrote an article a week ago. I think, there must be some mistakes here..

Mutiara Sis Aljufri airport or also known as MSAA will add 1 more airline from Lion group subsidiary, Batik Air. According to Batik Air plans, Batik air is going to fly Makassar - Palu - Makassar daily by 15th December 2014. At the moment, Batik air manager is waiting for a concession to finalize administrative condition for facile operational.

I mean, the plane is going to fly between those city start from 15th December..

Is it okay to use "by" on that bold sentence ?

You can use 'by' in this way by changing the order of the date: Makassar - Palu -Makassar by December 15th 2014.

Or alternatively: Makassar - Palu - Makassar by the 15th of December 2014.

I hope this helps!

Batik air manager is waiting for [STRIKE]a[/STRIKE] the concession to finalize administrative conditions for facile operational.

The underlined parts do not look right.
Are you not talking about the concession to fly into an airport?
What is 'facile operational'?
