List of companies that stopped flying over Ukraine pre-MH-17

[ihorjr]

Dear All,

For one of the projects I am involved in I need to collect data on what airlines stopped flying over Ukraine prior to the MH17 tragedy. Does anyone have an idea where such list can be acquired or can recommend some websites that may have this kind of information? Through google search I mostly find newspaper articles that say something like "British Airways stopped flying over Ukraine months before". But I need exact days.

Any advice will be appreciated.

Thanks!
