So, I'm going from London to Stockholm then directly to Beijing. Our corporate travel agents ignored my recommendation to book a (cheaper) LHR-ARN followed by ARN-(LHR)-PEK-LHR and instead booked me an LHR-ARN-LHR return (in ET) and an LHR-PEK-LHR (in CW). All on BA.
The timings are LHR-ARN (two days in Stockholm) ARN-LHR-PEK (week in Beijing) PEK-LHR. The connection time in LHR is 2h40m so it meets the LHR MCT.
I am expecting BA in Stockholm to be able to check my bags through to PEK since it's all operated and marketed by BA.
Am I right to think that I don't have any protection against a misconnect in LHR, because there are two separate tickets?
In practice, what does BA tend to do in such situation if you grovel - does anyone have any experience?
I already checked what the later OneWorld options are in case it all goes wrong
