DD,
This SHJ option came up before. At the time I could find no difference in the cost of a QR flight. I have just checked again against the parameters used previously, and the cost comes out at 337GBP. Please let me know if you can find it cheaper, since I intend to do this route again during the next 12 months. When the new Meridien opens on the East Coast, it will be a better way of getting there, since most airlines seem to shun FJR!
