Norwegian announce transatlantic routes from LGW

Norwegian DY announced their 3 transatlantic routes from LGW commencing July 2014.
LGW-FLL 2 x week mon & Fri 1555/2100 2230/1155+1
LGW-JFK 3 x week Tue, Thu & Sat 1710/2000 2130/0900+1
LGW-LAX 2 x week Wednesday & Sunday 1535/1835 2030/1500+1
Prices don't look too bad, the concern I feel is that all of this looks to be operated by a LGW based single B787. It does look as if they've allowed some time buffer in the schedule for delays etc, but if a flight goes tech it could throw the whole schedule into disaray. Given the recent fun and games they've had with their recently acquired 787's it will be interesting to see how this venture goes.
