I did a return Dub-LHR in Aer Space on Saturday first flight in and last out.
Both Airports I was let into fast track security and Lounge by just showing BP
Middle seat blocked both ways and the little headrest covers were on
Full on way out - mostly transfers from what I could tell. 1/4 on the in bound, but a dead heading captain was upgraded during boarding.
Got the breakfast in the morning. Standard. The FA did encourage others if they would like something and told it was part of their fare. On the way back I just grabbed a coke and malteasers.
Overhead bins were marked for row one on the outbound only

I was booking quite last minute so for me the price-point difference was enough to warrant giving it a try
