Some tourists like to see, during the holiday, more than just one Island of the Canary Islands. So they decide to do: Islands Hopping 
One possibility is by airplane. If we have to fly from one Island to the next, we go by Binter Canarias… Because Binter Flights are usually ontime, the crew is very friendly and the price for the tickets is okay.
Of course there is also the possibiliy by ferry. It’s also okay, but needs some more time… and not each person likes to be on the sea ( like me 
)
The choice of going by plane or by ferry, also depends on if you go just for one day or for a longer time…..
If you need a ticket from Binter Canarias, you can buy it online… or by the travel agent
