I have a SIN-CDG business class ticket on Thai Airways via BKK on Sep 30. I've decided to head straight to Berlin after arriving in CDG. Hence, I will be on LH 4311 that leaves at 0920 hrs. That means I have about a three hour transit at CDG's Terminal One.

Now my questions are:

(1) are there Star Alliance lounges with shower facilities at CDG? Which are they and near what gates?
(2) Would I be able to check-through all the way to TXL in Singapore?
(3) Can someone guide me through CDG when I get off the Thai aircraft? Where should I head to?

Finally, as I am flying through BKK a day after the new airport opens AND transiting at CDG, I am hesitant abt checking in my rollerboard and overnighter. I plan to carry them on to the business class cabin. It does sound like a hassle to drag the rollerboard through BKK and CDG, but I rather not lose my bags, especially at the start of my trip.

Best
