The livery of Iran Air tour is cool. I like MD-81. The special livery of Turkish Airlines "TROY" is also cool. There are many airlines in Istanbul. Istanbul is the crossroads of sky.
Will you be visiting the new airport? Is there likely to be much opportunities for spotting there? Be a shame if we couldn't see so much of some of these rare and exotic airlines any more.
I definitely will visit the new airport when the new spotting facilities are ready :) Hopefully it won't take too long till they're open for public. I know they are building a spotting place at the seaside.
