Currently there are very cheap flights from Milan (Italy) to Mahe (Seychelles). You’ll fly on Ethiopian Airlines and Emirates. These flights are not that comfortable as the travel time is between 20 and 40 hours. Further there may be 3 stops on the outbound and 2 stops on the inbound flights.
Since the price is very low, this may be an error. In case it is, the airlines may cancel the ticket. Therefore I’d recommend to wait at least for your E-Ticket before booking any hotels or further flights and activities.
