Cabin crew were OK, but the Airbus A300 (or was it A320 - I can't tell) - was rather old & as I had a window seat, prior to takeoff fr MAA-KUL, I observed the bolts on the wings had rusted - I study Materials Engineering at University... got me worried. The worst was upon thinking this, we encountered very very bad turbulence en-route over the Bay of Bengal. When we were served drinks, the drinks really lifted off the cup & into the air - like some photos we see in Space Shuttles. Then I came to thinking of the 'rusted' bolts on the wings... kept me fully awake & constantly looking out of the window until we landed 2 hours+ later. The flight was delayed for 1 hour+.

But the best thing is the friendly cabin crew & captain who apologised for the delay, turbulence etc etc....
