In the old days brochures for the winter season were issued in May, don't know what happens now. Today, with the Internet as the main source of supporting media, the long haul programme could come sooner than May or could be left for later.
The other possibility, due again to the Internet, is that there could be a mid or late summer launch of a long haul programme if the market demand is there and there might well be enough time to sell it with a time gap of 3 to 4 months. One B763 is confirmed, so it won't be long arriving and now it would be a question of how soon the second B763 is acquired. In any case a long haul programme could be launched anytime once they have both airframes confirmed.
No idea what destinations are planned but the logical ones are a combination of Carribean Islands, Florida and the Cruises. This represents a good concentration of resorts/attractions within a small area to get the variety to attract the punters and fill the planes.
