We are doing Best of Adriatic in October from Kentucky, typically thru Chicago or DC, and have been using United Airlines for travel recently. The return flight from Dubrovnic is over 26 hours at best. is there another option for departure that could be easily accessed by train from Dubrovnic, extending the stay another day or so?
You will likely find faster flights by flying first from Dubrovnik to Zagreb, and then continuing on from there. If you are willing to overnight in the city you connect through, the cost—and sometimes even the time—savings can justify overnighting in that city.
You also might take a look at what’s available from Zagreb to Cincinnati/Northern Kentucky (CVG) International Airport.

Yes, as Kenko suggests! In May 2023 we did just that. Flights home to TO from Dubrovnik were expensive, excessively long with 2 long layovers so we flew to Zagreb with Croatia Air, stayed overnight by the airport to catch our flight home at 8am. After the add’l expenses, we still saved $600 and the flight home was reasonable.
There are no trains in Dubrovnik, so it's either some sort of positioning flight as Kenko
and Marika have discussed, or a bus to get you some place else.
This general issue has been discussed many times in the forum, since Croatia is a
somewhat thin/long country and there are not that many transportation options from
the southern part of the country.
If you don't want to fly to Zagreb (it's worth a night or two), you can fly to Frankfurt
or Munich and be in a Lufthansa/United hub. There are flights back to Chicago or
Dulles from Frankfurt until 5pm, so you could conceivably do DBV-FRA-ORD-CVG in
one (very long) day. Otherwise, you're looking at spending a night in FRA or MUC.
Not knowing your date of travel, I see DBV-FRA-ORD-CIN departing 7:25am from
DBV and arriving CIN 4:52, overall elapsed time 15:27 on Oct 15. Or DBV-EWR-CVG
departing 9:15am arriving 6:45pm, 15:30 travel time. So not sure where you're getting
26+ hours from, and this is all Star Alliance.
