It certainly does appear to have been 'empty' on both sectors so while it does seem somewhat extravagant for their commercial people to visit BOH in that way, it must be a possibility I suppose. It's point of departure and destination from BOH might give a clue, if anyone knows.
And before anyone gets excited about the Vueling A320 which arrived at SEN a few days ago, it was for maintenance with ATC Lasham. I did speak with Vueling at last year's French Connect about SEN, but only to acquaint them with the developments there and I don't think any operational interest actually exists.
