[@Regitnui]They were an hour away by flight, according to [@Reflection] 's post, so I'd guess that was maybe 20 kilometers or more.  Flying pokemon would also be fairly common, as several people in this RP use them and they weren't out of place at the tavern, so just hearing one wouldn't be that strange.

We'll likely be done with our meeting before they arrive.  Plotwise, I'd guess that either they'll arrive afterward and chase us down, or attack us as we leave.  Maybe they have an agent or agents in the tavern or in town that could slow us enough for them to arrive.  I haven't talked with [@Reflection] about that plot idea yet, though.
