I believe there is still significant leakage from Bristol to the london airports for short haul and there is clearly many more destinations that can be served. Who would have thought 10 years ago that brs would have 4 weekly Basel service or 5 weekly Lisbon ? There clearly is demand and probably the question now is the choice of flight time , airline and airfare now. As for long haul scheduled I doubt it's a high priority now that Cardiff has Qatar plus the decision not to plan a runway extension probably makes the above discussion all a bit academic .
