Hi there,
There's a direct bus to Malaga from Torrox pueblo at 9.00am on Sunday 31st, gets in 10.40. There's no direct bus from Torrox to the airport but, the train from Maria Zambrano is very quick and cheap.
The pueblo bus leaves at 7.30am to the coast, and runs every 2 hours on a Sunday. You'll pick up plenty of Malaga-bound buses from there, that will certainly be on the Alsa site.
