I've not travelled via Paris Orly previously, so I'm hoping the learned folk on the BA forum can assist. I'm looking at a connectiion from IB to BA on separate tickets, with 1hr 20min between scheduled arrival and departure.

I'll won't have any checked-through baggage, and will be armed with my boarding pass, so barring any significant delays, is this a reasonable amount of time to transfer at ORY?

Many thanks in advance.
