Hi I've been nosey and looked at the link (well my son went to Mombasa earlier this year that's why I was in this forum

)
I have travelled on small planes to the Channel Islands (Trislander), and my advice, if you go on one of the smaller planes in the fleet, is to take sweeties to suck on take-off and landing, and also ear plugs as it is likely to be very noisy. When it says the planes do not have a cabin attendant, this is because there are only 2 seats in a row and no aisle, so it's a bit like flying in half a coach or bus. Remember to keep your sunglasses and camera handy.
The kids loved these flights more than normal 737 type planes.
Have fun
