My family and I recently flew on an expensive revenue based TFS-MAD with IB, connecting within 2.5 hours, BA MAD-LHR and a few issues arose which I would like help with:

1. Iberia had the TFS-MAD in their system at TFS but had no details on our connecting flight MAD-LHR hence could not issue MAD-LHR boarding passes. They even stated that the TFS-MAD boarding pass could be used for the LHR connection! How could this be? Surely this should never happen?
2. They could they check our baggage all the way to LHR? How could they do this when they could not see the whole booking?
3. The TFS IB flight, was delayed by 3 hours due a Ryanair plane stuck on the runway hence we were bused to Tenerife North where we eventually took off for MAD arriving considerably late. Iberia in MAD had no details of our onward connection, despite the same booking, although they did have details of 18 other passenger connections and helped them. How could this be? IB3911 has also disappeared from past performances as if it never took place? How come?
4. We were left to our own and managed the connection with 5 minutes to spare as BA465 was operating one hour late. We notified the BA gate staff that our inbound connection was very late and were ensured by the BA gate staff, twice, that all of our four checked bags were loaded in the BA0465 hold. How could this be, did they really know?
5. On arrival at LHR T5 we were informed that 2 of our 4 bags were not loaded at MAD and would be forwarded by courier. These did arrive 5 days latter but the suitcase integrated lock was broken on one of the cases.
6. My wife and children have now been credited with their Tier points and Avios points for both of these flights however my IB flight claim has been rejected twice by Iberia for the IB section. How could this be possible when we all travelled under the one booking and included Exec numbers for all passengers?

I am deeply concerned that having booked via British Airways then Iberia have no booking details which with, One World partners, should be seen as a seamless operation. My wife and children have been deeply distressed by these circumstances. I guess BA just does not share its database with other One World partners? What would of happened if we never arrived at LHR?

Finally as this was all booked under ba.com with a combined BA payment is the responsibility to resolve these issues resting with BA or can they just pass the buck to IB as is happening?

Any useful comments would be appreciated

Many thanks
