I tend to agree with you Longhu, we have wait years to see if this is important for the UK aviation history. What we will see from July though is a new price range on tickets across the Atlantic. As an example if you fly out on the first Norwegian flight to LAX and return four days later you will pay £300 less than on BA flights in Economy on the exact same dates (with the Norwegian the Plus package is included in the price). With BA you will fly with their new A380 and of course Norwegian fly the smaller B787, but both carriers rely on British engineering for their jet engines.
