re BRU and SN
To add to Peter's notes,
part of the truth behind a BRU service is the Welsh pax are travelling by mixed modes to BRU. Sure some are using the SN service, an element use KLM via AMS but most use either the Train via London or fly to AMS and catch the train.
I suspect SN are feeling the pinch at BRS from LH and AF dilluting yields and hub connections. This is why they have gone away from a night stopper and also reduced frequency. Nothing to do with changing times for Welsh pax. If that was the case, they would just fly to Wales instead. With LH looming as a new owner too, they might just pull out within the next 12 month anyway.
