Congratulations to the posters above who have missed the point of flywho.
If you are going for the lowest fare, it won't be flywho. They are offering a PREMIUM economy service - not an economy service - so comparing their fares with CO, VS or BA economy fares is not comparing like with like. Do a comparison between WTP (BA) or PE (VS) and you'll see lots in flywho's favour....
If you want to pay £300 to go back and forth to Florida in a seat marginally smaller than you are, with cardboard food - fine. That is just not the market flywho are trying to serve!
