The only good thing about Mango Airlines is the price. But that is if you are lucky enough to be able to get through to their website or call centre to actually make a booking!
Mango Airlines has said that they have increased the bandwidth of the site 4 times, as well as increasing staff at the call centre, but it still seems that things are going very slowly on both sides.
