Service-wise it's hit and miss. Delay-wise it's also a bit hit and miss, but if there's a delay it won't be for more than an hour or two.
Their 330s have angle-flat seats, while the 320s/321s have either a blocked middle or a 2+3 config with a slightly wider biz seat.

On visiting the Azores, fall is the best time to visit - it's still warm enough and usually not very rainy, no crowds, and the ocean water is warm enough to swim in (unlike in Continental Portugal). If you want to see no people, do a side trip to any other island. São Miguel (where PDL is) has 140k people, Terceira has about 50k, while others have 5-20k, so you'll likely see more cows than people
