Iberia Airlines Iberia Plus - Is this common? Iberia.com say's passenger is already checked-in, but isn't...

I am trying to do online check-in for a wholly-IB itinerary (ORY-MAD-EZE) that was booked via British Airways (redemption ticket). The web site kicks up the following message: "El pasajero ya se encuentra facturado" when I try to do check-in directly at Iberia.com, and gives the same message in English if I try to check-in via Manage My Booking at ba.com (which seems to transfer over to Iberia for the actual check-in attempt).

Is this normal? I know Iberia's reservation system is probably the worst in the world, but I've yet to encounter a situation where it won't let you check in, because it thinks you're already checked in, but in fact you're not checked in at all.

I'd like to sort it if possible, as the departure out of Paris is very early in the morning, so every minute may count from a sleep standpoint. The onward to Buenos Aires also might be rather busy due to the recent cancelations in relation to volcanic activity, so would be nice to get the old boarding pass for seat 1A and be done with it.

Any thoughts?

Yes it is a common problem for me, although normally only with another operated flight involved. Is there another operator involved, eg Vueling?

Check your account on BA.com, you should have 2 different PNRs. Try both of them in Iberia.com

The other problem that is common is Iberia.com will not let you checkin online because it wants to see your credit card so you have to do it at the desk. Oh, and entering your passport details - even on the return leg!

Checkin from London City is impossible because Iberia.com does not have it in its system and so it just fails, London City checkin cannot print Iberia boarding passes so it all has to be done at a customer service desk near the T4 security.

IME calling up customer services does not help one jot as they just tell you they cannot do anything.

Iberia.com = pile of sht although I noticed quite a few BA.com things worming their way in so maybe things are changing...

As a follow-on, I never did manage to get the passenger checked-in online, but did discover the following along the way:

Even though it was a BAEC booking, and passenger details such as passport number/country/expiration date are all stored in BAEC profile and applied to BA bookings, Iberia.com still asked for all these details - although it did seem to pretend to take us to the check-in page even though these hadn't been (re-)entered.

Both before and after re-entering these details, the same message saying that the passenger was already checked in when attempting to do the online check-in.

Only Iberia flights were involved - although the ticket number would have been a BA ticket number, since BAEC issued it (maybe this is actually the problem - has anyone managed to check-in on Iberia.com when holding a 125- ticket)?

Iberia.com's booking management did allow us to pre-select and change seat assignments, both for the ORY-MAD leg that had been booked in economy (no U available at time of booking) and for the MAD-EZE leg in business. With that said, however, only about half the time did the change seem to stick... For instance, I changed 7A to 12A (exit row) once, only to see the passenger back in 7A the next day. I changed it again, and there he stayed. Same situation with 5L to 1A on the long-haul segment.

Oh well - all is well that ends well. Even if the passenger did go to CDG in an early morning haze before realizing IB flies from ORY... but that's another story altogether.
