Identified as old logo of the Prague Airport (Thanks Ian !!!!!)

Identified as Paramount Airways (Thanks Dieter !!!!!)

Identified as Alisarda (Dieter, Thanks again !!!!!)

This logo has some similarity with the VIA Rail Canada logo, but I think it's not the same.

There are a lot of VIA logos but meantime no one is of airline:

The only VIA airline (as far as I know) is the Bulgarian "Air VIA" :

Airline logo ?

Is it any of the Midway airlines ?

Any idea ?
