Astra Airlines A320 IAE

2 corrections about the Greek flag:

- in total, it has 9 horizontal stripes, beginning and ending in blue.

you have out 8, beginning in blue and ending in white.

so you need to add one extra blue horizontal stripe at the bottom

- the upper-left square area with the cross, has a white cross in a blue background

you have the colors inverted -> blue cross in a white background

you have to invert the colors

And if you don't believe the above, search anywhere in the web for a picture of the Greek flag, or even better, see it on the original plane here:
