I have booked a BA holiday (flight & car) some months ago. When it came time to pay balance (I have) the outward leg looks like the screengrab below. My memory tells me I wouldn’t have booked such a tight connection but I could be wrong.

I can’t see any way I’ll make this connection but defer to group members. Suggestions welcome.

Assuming I miss the flight at LHR ☹️ what are my options and BA obligations?

Thanks all.
