Jethro's have G-FLBF/G/H/J as due in 2011 (G-FLBI is already issued to someone else)
You have overlooked G-JECV/W which left the fleet for Olympic and according to BE financials they were sold to them, are now on the Greek register, so presumably left permanently.
Like you, I assume the two ex-Wideroe's will go in the next few months, and there has been mention from within BE and elsewhere of G-JEDI leaving too, beginning the disposal of the oldest frames which are approaching 10 years.
However, I guess that with talk of takeovers, deals in Finland, and ambitions for provide feeder services elsewhere in Europe, precise numbers are bit fluid and they have to have some fleet flexibility.
Then you've got the E175's starting to flowin 2011, which will impact the Q400 fleet too................
