Could it be...
Could it be that the B763 is heading for Scandinavia and Britannia Airways Nordic (from 1st May: TUIfly Nordic)? The airline is expecting to operate a B763 for the autumn/winter '06-'07 as they have presented new longhaul nonstop charterdestinations from Scandinavia, to Venezuela, Brazil, UAE, Cap Verde Islands and Mauritius using several B757's and 1 B763 - the last a/c being a "new" addition to the fleet.
