A non pilot friend of mine was on a flight out of Afghanistan recently. She said that apparently civil flights are limited to max FL280 in afghan airspace and wanted to know why. I suggested it's some military restriction but it's o ly a guess. Anyone know the answer ?
Have crossed Afghanistan airspace above FL280 several times. Unless there has been a change recently (have not been in the area during the last 3 months), I don't know what your friend is talking about.
