I don't think that IAG will again make the mistake of competing with themselves in the UK.
I wouldn't be so sure. If the objective is to take on the likes of Norwegian I wouldn't be at all surprised to see Level turn up in the UK regions in the next couple of years. In the longer term perhaps even at LGW as well, although BA's move to "densify" it's 777 fleet by adding more seats would suggest there is no plan to introduce Level to LGW any time soon.
