Haven't been on here for ages...feel awful asking out of the blue but its a question I'm just not sure of.

Flying to Perth from LHR in March with BA (but on QF metal in Premium as it was 700 pounds cheaper booked this way!!). Land at Singapore and then have an onward flight booked with QF with the usual super quick transfer (75 mins I think but I always make it)

This time I have booked two separate tickets as it was so much cheaper but will get my luggage tagged through. IF the first plane is late getting to Singapore what will happen with my QF ticket seeing as it is a separate ticket? On the same ticket I know they will honour it and rebook me but not sure what the deal would be this way? I am contemplating staying over in Singapore as a precaution and flying the next day but would rather do the straight through option.

Appreciate any knowledgeable insights

Been living in the UK and flying a lot less but still check the forum for advice when I do travel. Moving back to Australia permanently this year so hope to catch some of you again for a beer
