My return from Brisbane (EK435) is at 20.45 on a Sunday night.
The non-stop flight is 14 hours 45 minutes.
I arrive Dubai at local time 5.30 am Monday.
My Dubai to London (EK001)departs 7.45 am.

When I do my OLCI at 24 hours out from the Brisbane departure, I can also check in for any connecting flight within 36 hours from the time I do the OLCI.

So doing OLCI at 24 hours before departure I can, in reality, check in for flights with a departure time within 12 hours from the departure time from Brisbane.

The flight for Brisbane takes 14 hours 45 minutes minutes so no I obviously cannot check in for the Dubai-London leg.

However the flight from Dubai, because of time zones, actually leaves 11 hours after my flight from Brisbane departs so yes I obviously can check in for it.

So the question is, which is it?

Can I OLCI for the Dubai - London leg or not when I do OLCI 24 hours before my Brisbane flight?

Thank you.

Others will be able to give a definitive answer but I have travelled from MEL to LGW via DXB on many occasions and have always been able to do OLCI for the whole trip - presuming that your ticket is actually Brisbane to London.

Flying from Auckland to Glasgow I have always been able to check in for the entire journey using OLCI 24 hours before AKL departure time and boarding pass printed with seat allocation for both flights.

Assuming both flights are on the same ticket, you will see both flights on OLCI 24 hours prior to BNE-DXB flight.

If they are separate tickets then you'd still be able to check in for the DXB-LHR flight while you're in BNE. Besides EK staff at BNE will be happy to assist with issuing the boarding passes for both flights and checking through your luggage anyways.

I think you might be reading too much into OLCI!
