Looking at a LH flight from CDG to FRA connecting to UA to Houston. Business class on both legs.

A few questions:

1. Does “domestic” business class get the access to premier security lines at CDG?

2. One of the potential flights is a CRJ 900. We have standard 21 inch (53 cm) roll aboard carry ons plus a small tote bag. Are they likely to fit in the overhead bins on the CRJ? Or do they do valet check so that we pick them up plane side on arrival in FRA.

3. Is an RJ pretty much guaranteed to park at a remote stand/bus gate in FRA?

The RJ flight would give us about 3.5 hours connection time.

The next one is an A320 and would give us 2hours 15 minutes connection in FRA, which should be doable and there’d be no worries about our carry one.

1. One last question. Most flights from CDG to FRA go into A gates. Some are “ASS” which I assume are remote/bus gates.

UA goes out of Z gates, which I think are immediately above the A gates? So, just follow the signs to Z? Passport check only? There shouldn’t be a full immigration check as we are arriving on a “domestic” flight.

Thank you.
