el ala - if it's feminine, why not la ala?
If we use las alas, then why not la ala? Does this have to do with the difficulty in sounding it out?

What about el dia? There is no difficulty sounding that out.
Then what about el dia?
Día is masculine.
El día.
Los días.
Don't be surprised if you see the rule violated often. After all, Spanish speakers don't always use perfect grammar any more than English speakers do.
Look at this wiki article:
El ala es una mano abierta cubierta por membrana (patagio), el vuelo es lento y de gran maniobrabilidad (a diferencia de las aves).
But in the picture adjacent to that sentence:

Example el aguila se lastimo la ala.
Yes it's the same as el agua which is also feminine, however, in the plural it's las aguas. I believe it might have something to do with cacophony, where the two a's mix with each other.
Ala puede ser femenino o masculino depende a lo q te quieres referir
Yes, you are correct in your suspicion that it has to do with sounding it out.
La ala would sound like "lala.'
We say las alas because the "s" in "las" removes this problem.
