Hi Aqeeb, I've just answered your email with details and recommendations based on your group's experience level.
Narco, there are indeed direct flights on Firefly from Penang to Phuket. We have a whole range of diving available from the island ranging from the sublime (Similans/Surins) to the lovely (Shark Point, Amenone Reef, the Bidas near Phi Phi) to easy dives with lots of fish for less experienced divers. I'm confident that we can find something that will meet your time frame and budget.
