Pelican Aviation is currently working as a charter company. However, they have recently opened service to Mafia Island. Depending on who you contact for tickets you can get a one way flight to Mafia Island for $100USD. Which is much better than all the alternatives. Contact either AFRO from Afros Beach Bungalows and Whale Shark Diving on Mafia Island by email, or contact the booking agent Robert via WhatsApp who I found had the best price. +255 712 022 446
