Thanks Serfty for the info.

I actually think the above route is invalid because there is no direct flight from LAX-BRU. Correct me if I'm mistaken.

So I'm thinking that seeming it's a surface sector as soon as I land in Europe, I might as well fly into LHR because I won't be slugged a departure tax as I'm not actually departing LHR, my next flight is CAI-MAD..... am I correct?

My very last question, if I do change my mind mid-way and want to re-route some segments, can I change 6 segments and get charged the one fee?

I'm just waiting for Three to activate international calling on my phone, I got an error when trying to call AA in Dallas.
