Nikolai - my post was just me making intelligent guesses as to where FR might consider using airframes that are not currently occupied in the timetable along with some sort of rationale. I don't have inside information, so am a little puzzled as to why you think my suggestions are almost certainly going to happen !
If anyone who has worked as a route planner would be kind enough to spare a few minutes to give their thoughts, I'd be genuinely interested to hear from them - see weblink
