Some carriers would prefer the aircraft they needs, In my own airline, I will have lots of Boeing Orders all the way until I'm filled up on my Routes, and Stocks.
When I looking at my airline schedule before it opens, I would count which route needs this planes.
For Honolulu, Hawaii, I will go for the 767-400s, 3 flights daily from every major hubs of my carrier.
If they(other airlines) prefers the A330, thats their problems.... But BOEING IS GROWING SUCCESSFULLY
But I have few Commuter Planes to choose from which is my Boeing B717 will be 1 to fly short flights as a commuter service, and not those ATR42, ATR72.. or any wing mounted commuter jets. EMB 170 / EMB 190 would be my favourite commuter fleets. I will choose what right for me !!!!
