I complained to a One World VP when IB refused to interline my bags. I asked him what the benefits of an airline alliance were if they wouldn't do this. He side stepped the issue and passed the buck to IB

Needless to say IB never responded.

The bag fiasco caused me to miss a long haul connection. Yes it's my risk to buy separate tix but it would not have happened had I not had to wait 40 mins for bags.
