(EasyJet bought a Swiss company (TEA) and EasyJet Switzerland doesn't seem to be doing too badly.)
It's a matter of public record that this was a seen later as a bad move. It would have been demonstrably better to start easyJet Switzerland as a new company from day one without trying to re-mould the existing culture into the Orange brand.
Still best not to learn from history. Let's throw some more random darts and let more people worry about their jobs. This thread has gone into fantasy land now.
