So... I'm flying EWR-FRA-CDG connecting to AirMadrid to MAD. Two completely different tickets. Questions:

1.) Does LH interline bags with AirMadrid, so I could check my bag all the way to EWR->MAD? If not, how do I collect in CDG?

2.) Anyone know what the respective locations of LH and AirMadrid are in CDG, and how difficult the connection is?

3.) I will be in F over the water and C to CDG. I assume that I can still NOT use the SEN lounge upon arrival in Paris? I have a three hour wait, and AirMadrid has no lounge.

4.) If the answer to #3 is NO, does anyone know if, during this connection, there is any way I could make it to the UA Red Carpet Club? I'm a member.

Thanks!
