Do you have Blue Card? If so, you might be able to protest to greater effect. But don't hold your breath.
If you whipped out a
Blue Card and played the DYKWIA game you wouldn't get much of a response.
Its a tricky time, plenty of teething issues to work through - IT being one of them. BD's computers barely functioned at the best of times. Asking them to talk to BA's systems and vice-versa is hugely tricky, especially when people are flying under both BD and BA PNRs.
Waiting an hour though is unacceptable, more desks should have been opened. Not sure about the handling situation in DUB but if BD were self handling I very much doubt BA would take on the staff/equipment; more likely they would put it out to a third party like they have done around the rest of the UK.
