My bad, skipped some posts I guess.No NCB, it will not be a BMI A319. Don't say things when you don't know the facts!
It will be a Belgian A319, OO registered, indeed in *A livery. And I shall give a little hint, it will be an a/c that already flew under OO registration based in Brussels
Good news then for SN, gradually replacing B737's in favour of A319.
A319 lease rates are slightly higher than B737's, but lease contracts aren't going to get any cheaper than they are these days, and the B737's will need to be replaced sooner or later, so definitely a good deal.
If they rotate A319 in the morning and Avro's in the afternoon, LHR should become profitable.
If SN could introduce some service to LCY it would be even better... If requested by competitors, aren't the AF group required to drop some slots at LCY due to their dominant position after the acquisition of VG?
The ERJ wetleases are perhaps the right capacity for the thin routes mentionned and probably better than bringing the Avro RJ's or BAe's.
