I was wondering if anyone had any experience with the same-day change on semi-flex domestic fares? In particular I was wondering whether BA consider EDI-LHR and EDI-LCY to be interchangeable (both being part of 'LON') or whether they were quite strict? I've gone for the later flight but if all goes well may be at EDI in plenty of time to make the earlier LCY flight but not the earlier LHR one and just wondered what folks experience had been.

Not a major problem if it's not possible - can always relax and enjoy the new EDI lounge
