Yesterday I was flying one segment CDG-DUB (of total Tempo PEK-CDG-DUB) and my boarding stub read Abonnes. No difference in my usual routine (more or less same seat in either row 4 or 5 either side just behind the ridiculous C cabin) weather it reads Abonnes or not so what is the difference?

The snack, drink and/or seat is the same as anyone else’s further back in the cabin...

The miles earned are that same (374 - i.e. 25% of 1,500 miles) so nothing new there...
