Very similar to the deal posted by boyaloud but for travel on 31st December. Same conditions apply:
Check your nectar account and this deal should be there. book on east coast Virgin site with your Nectar number entered. Book a child single from Edinburgh to Haymarket for that date even if you won't use it - get 1,000 points.
you must religiously keep records of ALL nectar offers you take up as they nearly always forget to award points. after 28 days you then go on live chat with them to get them put on.
Journey must be over £1 in value to trigger the deal.
