Honestly there are some sharks on here. The guy came on to a public forum and faced the critics (who are faceless and all powerful). Not having specific airline experience does not and should not rule somebody out, though clearly they need an experienced team around them to avoid expensive pitfalls etc.
We've come to a stage where the list of airlines has dwindled substantially and not withstanding the current challenges, there would seem to be few opportunities to viably enter the market. We need (imho) to welcome this development and clearly Eastern are a reputable and safe airline. That gives confidence and supporting a British airline ...
It's also a brave move to get into anything airline amidst this pandemic... so best of luck to those concerned.
