Not CWL bashing as I want it to succeed too but you have to be realistic. There are many reasons in business why ventures don’t progress. Airlines don’t exist to start routes to please us enthusiasts, they’re there to make money.
look at the QR flights. They’re postponed but do you realistically see them returning?
W6 will have weighed up the economics of CWL and had the demand been there, flights would now be running. They’re not. So they’re postponed until next year which suggests that demand is not yet there. Why would they expand if demand is not yet there for some of the most popular destinations?
