Picked up a AI flight at LHR to ORD on a 747-???. Flight originated in BOM. This was about 3 years ago.

Poop on the walls in the bathroom. Open suitcases in the aisles, on empty seats. Trash littered on seats, aisles and everywhere else. Children running back and forth up and down the aisles for all but an hour of the flight. Food service items not picked up for 2 hours after we ate. One drink service, one tea service, one water service. FAs refused to do anything. Told me to worry about myself only. Seats reclined and trays down on takeoff and landing. Worst flight ever. Funny thing is on the ORD-LHR leg two weeks earlier, it was one of the most pleasant coach flights ever, with fantastic service, excellent food and fantastically well-behaved customers.

I sent a letter to AI and the replied, quite briefly, with a response that stated they had spoken with the flight attendants on that flight and none of my complaints were experienced by the in-cabin crew. I considered writing the FAA or JAA but decided it wasn't worth it. Just made sure never to fly them again and sent a nasty-gram to UAL when I heard they were going to join *A. A real shame.
