What does "fare component" mean when they say "no stopovers on the fare component"? Is that the TATL flight? Or something else?
Also, my search is now showing "Iberia (IB) ILN8S4C1" on the fare rules & restrictions page rather than your ILN4S4Z1. Not sure there's a big difference here, or if its the same rules and restrictions just under Iberia rather than BA?
