Hi there fellow travelers, another odd ball situation has popped up, for whatever reason, I can't seem to avoid them. I'm currently in IAH waiting on a RT flight to RKE (Copenhagen, via LHR) I just found out I'm going to be needed in AMS (Amsterdam). I checked and of course BA wants to charge me $500 PLUS full fare to change my flight to AMS instead of RKE. I would be much cheaper to just book another flight directly from LHR to AMS since I have a layover already. Is there rules against not showing up for the second leg of a flight? I still have full intentions of flying back to IAH as planned (RKE>LHR>IAH). I have no checked bags, only carry ons. I even have tons of Avios I could use in a pinch. Any thoughts or help?? Thanks!
