LOT ceased the WAW-LYS operations last year, and I want to be in Lyon at the end of October to 6 of November. Help me to choose a good Skyteam airline to fly from WAW-LYS:

-I am a Vietnam Airlines GLP GOLD member
-I want to have a cheap ticket but
-What I have to do to enter the lounge in CDG because I am Elite (GLP GOLD)
-Air France offers a Prenium class (AF in advertisements revealed that in Prenium with cheap prices (Y Class) and it is Prenium Business which is expensive.
-Do I have a baggage tag? for priority baggage collecting

Thanks. !
