I've been planning a AONE4 for later this year, and I was thinking it would be nice to stop by Gibraltar. The on-line Oneworld booking tool let's me get there, but no matter what I try, it won't let me leave. Kind of like a roach motel (the roaches check in, but they never check out). WTH? If I say I'll do a surface segment to Malaga, everything is fine. Is there something special about Gibraltar when on RTW fares?
