From all my experiences of them, Norwegian has proved to be a really very good shorthaul airline. The longhaul venture was, at best, a ‘brave’ one, though, and their costs were far too high.
Worse, the strong reputation that they have for shorthaul was in real danger of being permanently compromised by the generally dismal service levels of the longhaul operation (I’m not talking about staff service here; I mean the unreliability of operations and limited to zero contingency).
I’m naturally very sad that the Gatwick longhaul base is closing, and I know one of the senior people there, too, but I can’t help feeling that it was always an ill-starred venture and it’s demise might at least help assure the shorthaul ops - and protect and grow the jobs there as the industry restarts.
