Can I correct you (if I may), the number of JET2 aircraft to be based at Leeds was going to be SIX for the summer season, but I understand this now to be SEVEN, not eight as you suggest. TWO aircraft are said to be basing at BFS, one of which its primory role will be a nightly fraight run and the other daytime sector will be as you suggest operating the Prague service.
This would leave one extra aircraft at BFS, possibly to operate other NEW services.
