I fly FRA-PVG with *Alliance-Partner CA in August (because CA got very cheap one-way-flights).
Is it still possible to enter LH-Lounges as FTL with a *Alliance-Partner-Ticket?

If not: I got a FTL-credit card with AIRplus-option, which offers AIRplus-Lounge entrance for an extra charge? Are the AIRplus-lounges a good deal?

Cheers
Tim
