Excellent, thank you for your responses. Will definitely monitor my bag. I've had numerous longer transfers with QR and haven't had issues but this is the first one that will almost go up to 24hrs so just wanted to check.

Regarding PCR, I'm travelling BEG-DOH-SIN. I do need a PCR but thankfully, here it is a really easy process, with results on the same day and it is rather cheap. I registered for entry into Qatar and got approval in less than 5 minutes although it does mention in the approval to have a PCR with me taken up to 48 hours before.
