First off welcome.

Second, there is no such aircraft as the Boeing 330. The 330 is made by Airbus.

Finally, I tend to go for the window when I travel with pups if possible even though I personally hate the window. My reason is this: sitting in the aisle means I will have people in the window or middle seat wanting to get out and I run the risk of pups getting kicked.

If you are on a 330 (Airbus) the configuration is 2 x 4 x 2. That means every row has two window seats, four aisle seats and two middle seats. Good luck.
