A look at the past all business class offering from KLM and now from SAS on PrivatAir 737 aircraft, are indicators of the demand for a premium product from Europe to Houston. With SQs reputable offering, perhaps they feel that they are on to something but it could be argued that the route would be attracting passengers outwith the Manchester catchment area, who are going to Houston. I suspect that codesharing outside of Star would be the only solution to ensure sufficient connectivity, if this was to go ahead.
