Rather calmer than the chaotic CDG Orly resembles a pre-1980s Heathrow Terminal 2 (simple beige interiors lots of windows). There's even a viewing terrace for spectators. On transport links though it's often suggested people should take RER B to Antony and then the ORLYVAL shuttle train this is a rip-off option. RER B to Antony takes a while from Central Paris and is often is packed out taking commuters into the southern suburbs whilst the ORLYVAL is a rip off. It's pleasanter cheaper (and from experience quicker) to get the more comfortable RER C to Rungis and then the shuttle bus to Orly.
