No problem and thanks for the clarification. Separate question. If there are two segments of a flight, both operated by Iberia, both covered by a SINGLE E-ticket number, but one segment is a BA flight code with BA online check-in code), and the other an Iberia flight code (with Iberia online check-in code), will I be able to through check my bag to the final destination, given that the "online check in codes" are different? As the example only, the segments could be ORD (chicago) - LHR (london) - (BOM) Mumbai?
