Airline Name: PrAirie
Airline type (flag carrier, legacy, regional etc): Global network based in grassland/plains regions of the world
Country: Central & Southern Russia, Sub Saharan Africa, Argentina, Midwest US and Canada, Southwest Australia & most of continental Europe (for open world lol)
Aircraft (Please pick from one of Med's wonderful templates): 707-320B
Aircraft Registration: Any is fine
Logo (describe it or upload an example): Don't have a logo concept, maybe something abstract like long grasses blowing in the wind
Colour scheme: Golden yellows and pale greens
What you'd like the livery to be like: I like your examples with color blocked sections but perhaps something a bit more asymmetrical. Maybe the colors are close in value so there isn't a high contrast effect.
(The more detailed the better, use bits and pieces from real airlines of the time if you like)
Thanks hope I'm not too vague!
