The 900 issues are somewhat overblown in my opinion. Based on my experience in the aircraft (4 years and 3k hours) the issues most often come down to the following:

1) Using the aircraft on routes it's really not designed to do, although I've done TLV - JFK and BOS several times at max gross weight, full pax when very hot and been just fine. That route is probably around the expected limit of the airframe with full pax and any alternate fuel anyhow. I don't think Airbus engineered the A330 for US - Asia markets.
2) SLC - The limitation there was due to takeoffs with abnormal bleed configuration (bleeds not on engines for max performance) which created some downrange issues. This was removed over a year ago and no longer nearly as limiting in most cases, as far as I've seen.
3) Tailwind / high crosswind takeoffs - This is by far the most limiting factor I've seen that comes up most often and the one I will agree is a bit of a black eye on the airframe...even though its actually and engine limitation. The Rolls engines have a procedure that must be applied with tailwind takeoff or crosswind over 20 Knots. You must accelerate to 30 kts ground speed at 50% N1 before applying takeoff power with ANY tailwind, which can be an issue with some runways, especially hot and high, short, or contamination. Some airports we frequent routinely use runway configurations where tailwind takeoffs are the norm and these will be an issue for the 900, especially on long range routes / heavy weight departures. That said, SOME of this can be mitigated by the next;
4) Some of it is pilot induced - not understanding the WDR, specifically the ***Overweight*** indication for a runway doesn't mean the aircraft is actually overweight.......good numbers can be received via TOPR. I have witnessed this on multiple occasions, most often runway 25 in LIRF when pilots defer to using 16R with a delay when numbers for 25 are available via TOPR.

I understand others may have experiences where the 330 has been more limited, but that overwhelmingly hasn't been my experience when the aircraft is operated as designed, using all tools available on routes it is designed for.
