The Bay of Bengal/Andaman Sea is crap for turbulence.
I was once on a KL flight from LHR which got into the worst CAT I've ever known. An unsecured trolley cart wrought havoc in the next compartment. The plane was pitching all over the shop.
I was just sitting there with eyes tightly closed and 'doing a
G SXTY', IE marvelling about what a superb bit of kit the 744 is.
The turbulence was that severe that the pilot started heading east towards Burma and ended up flying a ruddy great arc around the CAT. The route looked quite odd on the flytracker! Five or six people, including a CC member, were walking wounded when we got into KL.
I don't mind spiders.
