As annoying that it is when guests check out late, unless they really will cause a problem in turn around I would ignore it and move on.
Airbnb do allow you to charge +2 times ( double ) your nightly rate for any part of a 24 hour overstay period - including late check-out, but I think you need to be clear whether you will implement this or not (Terms 8.2.2 ). If you do want to implement this (and you can anyway), I'd make a point of ensuring the guest knew this would happen beforehand so that they knew what was coming... I think you will get an idea about some guests hankering after a late check-out. In our case a message (via Airbnb) would be "Hi, just checking with you about check-out time.. Check-out is 11.00am. Checking out later than 11.00am will incur a late check-out fee of £470 in line with Airbnb terms. We have a tight schedule today, so we'll see you at 11.00 when we collect the keys... Thanks!"
If you implement a punitive charge for late check-out, you then need to stipulate the notice required for this - otherwise you will have guests insisting that they are entitled to stay longer for (say) $10.
As a host, you know the scenario... otherwise great guests, overstay, doesn't really impact your day, you charge $10, they dislike that you charged them, you then get penalised in the review and your claim for an overstay of $10 is rebuked and you get $5. You then question was it worth it? If necessary, my preferred option would be to make the risk worth it and shoot for contracted Airbnb late check-out terms
Nobody has gone later than an hour late with us, none have yet caused any problem, but guests leaving on a tightly scheduled turnaround get told that check-out is required to be prompt and we'll be insisting they leave on time.
A recent group scheduled to leave at 11.00am didn't wake until 10.45 after I messaged them (via Airbnb) and woke them. They said they were just going to make breakfast. I told them they weren't, they didn't have time. They left by 11.23.
