If SEN was showing positive results on the sole JER route BE would have been interested. Simples. All the indicators to date would show that SEN doing well on sun routes, and a few city destinations added in. Loads have been superb on the sun routes and the domestics a flop. BFS being pulled and EDI not breaking any delph. I'd say the timing for flybe given their fare structure is not right. If I were in their shoes I wouldn't have touched it. That said , I think the airport is great, quick and convenient though I'd say hasn't captured much in the way of business travellers apart maybe from AMS route...
