I would pronounce it as you do, A-lah. Another pronounciation might be AH-lah. I heard the name
Ava pronounced that way the other day, as in AH-vah. (I personally pronounce it A-vah). I don't like the spelling Aila, it looks weird to me. I don't particularly like the name either, its not really my style.
