thanks for the clarification. So I should never purchase a “plus” fare if using LHR as an international connection? Is there ever a way to SDC easily other than toss the old ticket and purchase a new?

im flying back today, MUC-LHR and of course LHR is a mess. Have a J ticket and tried very hard to take an earlier flight back to LHR since everything is so messed up, but even with space available the agent refused without purchasing a new ticket. I would’ve gone over to EasyJet, who is still functional, but was worried about forfeiting my LHR-SEA segment.

With the last 6 (9? 12?) months of headaches through LHR we are going to avoid BA for awhile. With status, SDC’s are fairly simple on other airlines. Why does BA make things so difficult!
