Killing time in CDG
 

I'm arriving in Terminal 2A (US Airways) at 8:30am and flying out of Terminal 3 at 2:30pm. Any advice on how to kill time in between?

I'm thinking of staying in the Air Canada or American Airlines lounge in Terminal 2A upon arrival, but I'm guessing any checked bags will be sitting out for hours in that case.

It's not possible : you can't go airside if you're not departing. Arriving and departing pax are segregated.
Why not store your bags at the facility above the train station (in the middle of term 2 complex) and go to the Air&space museum at Le Bourget airport ?

Thanks for the info. Is there anything else to do on the arrival side without leaving the airport?

If you hang around in the arrivals area for long enough, I'm sure some people will turn up and invite you for a chat....

Once you're off the plane, you'll be directed to either immigration, or transfer security, depending on what signs you follow. After immigration is baggage claim, then customs, but unlike in the states you don't need to fill out forms or queue up for customs, just walk through + stop if asked. There are toilets in the arrivals side, but that's about it. All other services are landside.

If you wanted to catch a nap and shower, the Ibis Hotel on the airport will sell you a day room for 14€/hour (subject to availability; no reservation allowed).

Sorry, but I can't think of anything ! Are you thinking about something in particular ?

Thanks. This is this the kind of information was looking for.

Just wanted a comfortable place to kill time until the next flight, unless there is something interesting to do in the airport.
