Max flight layover length still considered same flight?
Apologies if this isn't the correct place to ask this....
Does anyone know how long a flight layover can be while still being considered the same flight? On some "you can't get there from here" flights I've seen layovers of 19-27 hours... I'm wondering how long of a layover you could conceivably have (with any airline, to any destination) without having to buy a separate flight? I assume that one ticket (A - layover B - C) would be less expensive than two separate tickets (A - B, B - C) (?). Thanks in advance!
