Pity about Norwegian.
On the other hand I can't help thinking that what with the weaker pound, TCX and Virgin's own expansion plans, and AA/UA already contracting in the UK regions, the addition of Norwegian into the fray might have all proved a bit too much capacity for this summer. If the 17.8% capacity increase indicated by slot filings comes to fruition, that's still a very healthy growth.
Maybe NO will give MAN another shot in 2018, assuming they don't get Trumped in the meantime.
