I think Riga will survive - it seems to be used by people from all over the three Baltic states (possibly the reason Wizz had trouble breaking into the market with the Vilnius flights). I think these flights are all about reputation, a bit like flights to islands. Once a reputation is built up it is hard to compete. Anecdotally, I have a Romanian friend who isn't a big fan of Wizz but refuses to use Blue Air due to their poor reputation for reliability. Doesn't help, along with the other issues mentioned above. Does anyone know how the Wizz loads are to OTP?
