Luggage for ST Elite on an SQ segment
On a return leg of my AF itinerary, the first segment is operated by SQ. It is not listed as a codeshare, and only has a SQ flight number. The whole itinerary is a Light fare. As far as I understand, SkyTeam Elite status would allow me to check in a bag, but would I have problems with that on the SQ-operated flight?
What about the lounge access for that segment?
