The question is whether you feel it's reasonable. If you do, then carrying that logic through and considering your additional costs in getting to UAE, you might consider an entirely different route with some other carrier. But if we're talking mileage runs, where aiming for the lowest cost per TP/mile is the goal, then the advice has to be stick with Abu Dhabi.

There again, we're a funny lot on FT, and bagging a flight on UL's A330 might well float one of your boats. If it does, and you have the readies, forget the nonsense above and go for it!
