MD80fanatic,
Sorry if you can't understand the feeling! Can't blame you if you haven't been there!
It's not about the off time! It's not about how little we fly! It's simply about human psychology! Whether you fly 10 or 5 or 3 times a month, it doesn't matter! Any human being, flying throgh the night, where your clock say you should be sleeping will be fatiqued!!
But thanks for your contribution!!
